Greetings from Iceland. Perhaps you noticed that this picture is in fact not Iceland, but that’s only because I simply haven’t had a chance to process my images from the past week. There are many reasons to visit Iceland in winter, and I will very enthusiastically share examples in future posts (northern lights, anyone?), but today I’m sharing one more image from last month’s Yosemite workshop. And because I’m fully immersed in a workshop that occupies me day and night (chasing the low light by day, and the aurora by night), I’m dusting off (and polishing up) a post on a topic that is as important to me today as it was when I wrote it 12 years ago.
Let’s Get Vertical
Who had the bright idea to label horizontal images “landscape,” and vertical images “portrait”? To that person let me just say, “Huh?” As a landscape-only photographer, about half of my images use “portrait” orientation. I wonder if this naming bias subconsciously encourages photographers to default to a horizontal orientation for their landscape images, even when a vertical orientation might be best.
Every image possesses an implicit visual flow that’s independent of the eyes’ movement between the scene’s elements. Understanding that the long side of an image subtly encourages the visual motion through the frame—left/right in a horizontal image, up/down in a vertical image—photographers can choose visual symmetry or tension with the visual movement between the scene’s visible elements.
For example, because a waterfall flows down, orienting a waterfall image vertically complements the water’s motion, instilling a feeling of calm. Conversely, a waterfall image that’s oriented horizontally can possess more visual tension because of the natural inclination for the eye to move laterally in a horizontally oriented image. While there’s no absolute best way to orient a waterfall image (or any other scene), you need to understand that there is a choice, and that choice matters.
By moving the eye from front to back, vertical images can enhance the illusion of depth so important in a two-dimensional photo. Even though a still image lacks the depth dimension, there’s a sense that distance increases from the bottom up in its 2-dimensional world. The viewer’s eye is drawn first to a strong visual element in the foreground, then naturally flows up, and away, from there. The left/right tug of a horizontal image conflicts with this. (Many factors go into creating the illusion of depth, so I’m not saying that horizontal images inherently lack depth.)
More than just guiding the eye through the frame, vertical orientation narrows the frame, enabling us to eliminate distractions or less compelling objects left and right of the prime subject(s). Vertical is also my preferred orientation when I want to emphasize a sky full of stars, dramatic clouds and color, or (as I was reminded earlier this week) an aurora that rockets skyward.
In these scenes with especially dramatic skies, not only do I orient them vertically, I put the horizon near the bottom of the frame to further underscore the drama. When the sky is dull and all the visual action is in the landscape, I’ll put the horizon at the top of my frame. And when the landscape and sky are equally compelling, I have no problem splitting the frame in the middle (regardless of what the photo club rule “experts” might proclaim).
While a horizontally oriented scene is often the best way to convey the sweeping majesty of a broad landscape, I particularly enjoy guiding and focusing the eye with vertical compositions of traditionally horizontal scenes. Tunnel View in Yosemite, where I think photographers tend to compose too wide, is a great example. The scene left of El Capitan and right of Cathedral Rocks can’t compete with the El Capitan, Half Dome, Bridalveil Fall triumvirate, yet the world is full of too-wide Tunnel View images that shrink this trio to include (relatively) nondescript granite that can’t hold a candle to the main scene.
When the foreground and sky aren’t particularly interesting, I tend to shoot fairly tight horizontal compositions at Tunnel View. But when a spectacular Yosemite sky, snow-laden trees, or cloud-filled valley below demand attention, vertical is my go-to orientation because it frees me to celebrate the scene’s drama without diluting it.
When I composed the scene in this image, the moon had just popped out of the clouds. Knowing when and where it was supposed to arrive, I’d been set up with my Sony a7R IV mounted with my Sony 200-600 lens and 2X Teleconverter, hoping to capture the moon BIG as it edged up from behind El Capitan. When the clouds threatened to completely wipe out the moonrise, I’d have been thrilled with any lunar appearance. By the time this wish was fulfilled, I’d long since abandoned my big moon plan and switched to my Sony 24-105 lens.
Because the clouds and color stretched across the sky, and Bridalveil Fall was flowing nicely, I naturally did a horizontal composition of this scene wide enough to include all the good stuff. But that composition shrunk the moon to more of a strong accent, and I wanted something with the moon more front-and-center.
Moonrise and Clouds, Tunnel View, Yosemite
Flipping my camera to vertical, I increased my focal length to limit my terrestrial subjects the business end of El Capitan, with an incognito Half Dome lurking in the background. The longer focal length enlarged the moon enough that, while not the BIG moon I’d once imagined, it stands out far more prominently than it does in my horizontal version.
Breaking News
The night before last, my Iceland workshop group was treated to what may have been the most spectacular northern lights display I’ve ever witnessed. Until last night, when we topped it. Stay tuned to this channel for images (as soon as I get a chance to process them and write some—by my next blog, I hope).

Nature’s Gifts: Reflections

Sometimes Nature delivers us something that’s so beautiful, it just has to be a gift. When we think of Nature’s gifts, it’s often in terms of locations, like Yosemite or Grand Canyon (gifts indeed!). But today I’m thinking about Nature’s transient beauty: the perfect arc and vivid colors of a rainbow, a brilliant crimson sunrise or sunset, or an aurora dancing among the stars (I could go on)—beauty that can simultaneously surprise and wow us.
Underrated on Nature’s list of gifts are reflections. Doubling the scene, reflections signal tranquility. And like a metaphor that engages the brain in ways different than we’re accustomed, a reflection is an indirect representation that can be more powerful than its literal double. Rather than allowing us to process the scene directly, a reflection challenges us to mentally reassemble its reverse world, and in the process perhaps see the scene a little differently.
Reflections can feel like a fortuitous gift that we just stumbled upon. But given that reflections are entirely beholden to the laws of physics, they’re far more predictable than many of the natural phenomena we photograph. Taking a little time to understand the nature of reflections and how they’re revealed by a camera enables photographers to anticipate their appearance and craft their relationship to the surrounding landscape in an image.
Without getting too far into the physics of light, it’s important to understand that every object we see (and photograph) that doesn’t generate its own light, comes to us courtesy of reflected light. In other words, what we call a reflection is in fact re-reflected light (reflected first from the object itself, then by the water).
For example, when sunlight strikes El Capitan in Yosemite, some of the sun’s photons bounce back into our eyes, and there it is. But other photons head off in different directions—some to be captured by different sets of eyes, while others land on the surface of the Merced River far below. A few of these photons penetrate the water, illuminating leaves and rocks on the submerged riverbed, while others carom off the water at the same angle at which they struck—only in the other direction, much the way a pool ball ricochets off the pool table’s cushion. When our eyes are in the path of these bounced photons, we see a reflection.
The recipe for a mirror reflection
Water reflections come in many forms, from a mirror-sharp inverted mountain peak glistening atop a still pool, to an abstract shuffle of color and texture on an undulating lake. Both have their place in creative photography.
Autumn Reflection, El Capitan and Three Brothers, Yosemite
The ideal recipe for a mirror reflection is pretty simple: still water, a sunlit subject that’s much brighter than the water’s surface (the greater the contrast the better), and a view angle that matches the angle at which the sunlight struck the water’s surface. And while a sunlit subject and shaded surface aren’t essential, the more photons striking the reflected subject, and the fewer non-reflected photons (ambient light) striking the reflective surface, the greater the contrast that helps the reflection stand out.
El Capitan Autumn Leaves, Yosemite: With El Capitan getting direct sunlight and the slow moving Merced River still shaded, I had the sharp reflection I hoped for. With just a little bit of searching, I positioned myself to include nearby floating autumn leaves.
Playing the angles
Just because you don’t see a reflection in the still water in front of you, doesn’t mean there’s no reflection—it just means you’re viewing from the wrong angle.
Understanding that reflected photons leave the water’s surface at the same angle at which they arrive—imagine the way a tennis player anticipates the ball’s bounce to get in position—allows us to position ourselves to photograph the reflection we want. For example, if the angle from your subject to the water is 40 degrees, its reflection will bounce off the water at 40 degrees in the other direction.
Sunset Palette, Half Dome from Sentinel Dome, Yosemite
To locate the reflection, set your camera aside and move up/down, backward/forward, and left/right until you see find it. Then bring your camera back in and position it exactly where your eyes were when you saw the reflection.
Half Dome from Sentinel Dome, Yosemite: One summer evening I found myself atop Sentinel Dome shortly after an intense rain shower had turned indentations in the granite into small, reflective pools. Seeing the potential for a spectacular sunset above Half Dome, I wanted to include the colorful clouds reflected in the pools. At eye-level the pools reflected nothing but empty sky, so I dropped my tripod almost to granite level until my lens found the angle that intercepted the red clouds just above Half Dome bouncing off the still water.
When the water’s in motion
As spectacular as a crisp, still water mirror reflection is, it’s easy to overlook the visual potential of a reflection that’s not crisp, and to forget your camera’s ability to render a soft or abstract reflection much better than your eyes view it.
Before the Sun, South Tufa, Mono Lake
While a crisp reflection can dominate an image, a splash of reflected color or shape can beautifully accent a striking primary subject. And a reflection that’s lost to the continuously varying angles of rippled or choppy water, magically appears as a soft outline when a long exposure smooths the water’s surface into a gauzy haze.
South Tufa, Mono Lake: In this sunrise image, all the ingredients were in place for a special reflection. Just as the color arrived, a light breeze stirred the lake’s surface with gentle undulations. I used a 6-stop neutral density filter to enable a multi-second exposure that completely smoothed the lake’s surface. While not a perfect mirror, the resulting reflection has a very pleasing soft, gauzy look.
Autumn Reflection, El Capitan, Yosemite
Where to focus
An often misunderstood aspect of reflection photography is where to focus. Though counterintuitive to some, the focus point of a reflection is the reflection’s subject, not the surface it reflects on. This isn’t a big deal when the focus point of everything of visual significance is infinity, but it’s a very big deal when you want both your distant subject’s reflection and the nearby rocks or leaves on or in the water surface to be sharp.
Photographing a distant subject reflecting in a pool of leaves requires the same hyperfocal depth of field approach you’d use for any other close-to-distant image: small aperture and a focus point slightly beyond the closest thing that needs to be sharp.
El Capitan Reflection, Yosemite: Photographing autumn leaves atop El Capitan’s reflection required impossible depth of field to capture sharpness throughout. Even though the leaves and reflection were just a few feet in front of me, focusing for a sharp reflection would have softened the leaves. To increase my depth of field, I stopped down to f/18 and focused toward the back of the closest group of leaves, then magnified the image on my LCD to verify that all of the leaves were sharp. Though El Capitan’s reflection is slightly soft, a soft reflection is almost always more forgivable than a soft foreground.
Polarizer
Reflection on the Rocks, Lake Wanaka, New Zealand
Put simply, a polarizer cuts reflections. Most photographers use a polarizer to darken the sky, and while that can be a nice effect, the polarizer’s value is far greater than that. More than to darken the sky, polarizers remove subtle reflective sheen that washes out color on foliage and rocks.
An underappreciated polarizer use is to erase a reflection to reveal submerged rocks, leaves, and texture. After photographing a reflection with no polarizer or polarization minimized (maximum reflection), rotate the polarizer to minimize the reflection (maximum polarization) and capture submerged features hidden by the reflection. You might be surprised by how different the two images are, and how much you like both versions.
Lake Wanaka, New Zealand: But a polarizer isn’t an all or nothing tool. When photographing the solitary willow tree in Lake Wanaka, I carefully watched the reflection in my viewfinder while rotating my polarizer, stopping when I reached a polarization midpoint that included some reflection, while still revealing the mosaic of stones just beneath the lake’s surface.
Rainbows
Rainbows are a very special kind of reflection that happens when light is refracted (separated into its colorful wavelengths) upon entering airborne water droplets. This refracted light reflects off the back of the droplet to create a rainbow.
Because the laws of physics apply to all reflections, we know that a rainbow would actually form a full, 42 degree circle if it didn’t encounter the horizon. The center of this circle is at the anti-solar point—the point exactly opposite the sun (with your back to the sun, imagine a line from the sun through the back of your head and exiting between your eyes). That means that your shadow will always point at the rainbow’s apex. And the lower the sun, the higher the apex will be. Read more about rainbows.
Rainbow Bridge, Colorado River, Grand Canyon
Double Rainbow, Colorado River, Grand Canyon: Understanding rainbow physics allowed me to anticipate a rainbow despite a black cloud blocking the sun and drenching everyone in my raft trip group. When I saw that the sun was about to pop out of the cloud and into a large patch of blue sky, I rallied my group and pointed to where the rainbow would appear. A few minutes later their skepticism turned to ecstasy when we all started capturing images of a double rainbow bridging the Grand Canyon.
Outside the box
Reflections also provide wonderful creative opportunities. An often overlooked opportunity is the potential found in reflections that aren’t mirror-like. And, in addition to the more conventional reflection composition that’s split somewhere near the middle to give more or less equal frame real estate to the subject and its reflection, some of the most creative reflection images concentrate entirely, or almost entirely, on the reflection.
Autumn on Ice, El Capitan Reflection, Yosemite
I found this El Capitan reflection at Cathedral Beach on the final afternoon of last month’s Yosemite Winter Moon photo workshop. After capturing a crisp, top-to-bottom El Capitan reflection, I repositioned myself to juxtapose much of El Capitan against the faceted veneer of ice topping the river. An added bonus of water still enough for ice to form was that it allowed drifting, recently fallen autumn leaves to settle and accumulate on the river-bottom here.
Finding the best spot combine the reflection, ice, and leaves in a single frame, I dropped low enough to get a sharp reflection El Capitan’s nose in the still, iceless water close to the shore. To ensure sharpness in the ice and the reflection (as well as the distant trees and El Capitan), I stopped down to f/18 and focused midway into the ice.
Almost all of the foreground was shaded, but with bright, direct sunlight brightening the clouds and El Capitan, this scene’s dynamic range was a real factor. But my reflection-centric composition eliminated the clouds brightest granite, making the exposure much easier. Finally, I tried multiple polarizer positions until I found the one with the best combination of reflection and submerged leaves.
Sunset Mirror, Yosemit
I was so focused on the other visual elements in this scene, I didn’t fully appreciate the bare trees across the river. But when I started processing the image and viewed it on my large monitor, I was pleased by how much they add to the wintry feel of this image.
Double your pleasure
Whether it’s a shimmering mirror, a gauzy haze of color and shape, or a colorful rainbow, reflections are a gift from Nature—camera or not. By doubling the beauty surrounding us, reflections have the power to elevate ordinary to beautiful, and beautiful to extraordinary.
For photographers, reflections provide boundless creative opportunities. When exploring outdoors with a camera, some reflections seem to jump out and grab us by the eyeballs, while others require a little more work. Either way, when properly conceived and executed, a reflection image possesses a visual synergy, conveying beauty that more than doubles the scene’s two halves.

Putting It All Together

ISO 100
Nature’s most spectacular visual moments come thanks to the glorious confluence of its static and dynamic beauty. Nature’s static beauty is its fixed features, the mountains, oceans, lakes, rivers, trees (and more) that inspire us to travel great distances with our cameras, confident in the knowledge that they’ll be there when we arrive. Nature’s dynamic beauty is its transient elements, like the light, clouds, color, weather, and celestial objects, that we try to anticipate—but that often surprises/disappoints us.
Whether it’s lightning at the Grand Canyon, the Milky Way in New Zealand, the northern lights in Iceland, or a moonrise above Yosemite, my photo trips are (selfishly) timed to maximize my chance for those times when the inherently beautiful scenes are blessed with special conditions. And though relying on the fickle whims of Mother Nature means the disappointments are frequent and frustrating, I’ve learned to roll with them because the thrill of success is greater than the frustration of failure.
But for a photographer, just being there isn’t enough, because, as thrilling as the moment might be, doing it justice with a camera usually requires more than just a simple point and click. Often (usually?), adding the best of Nature’s dynamic elements changes the scene enough to actually shift the balance of visual power—what might be the best picture in more typical conditions, suddenly takes backseat to the ephemeral beauty unfolding before us.
Getting the most from Nature’s glorious confluences means quickly identifying the scene’s best features right now, and finding a composition that emphasizes them—even if that means deemphasizing the static element that drew you in the first place. For example, at Valley View in Yosemite, photographers can choose between El Capitan, Bridalveil Fall, or both of the above (not to mention Cathedral Rocks, Leaning Tower, and Ribbon Fall). As I recently blogged, I’ll photograph this scene completely differently depending on the conditions—sometimes ignoring El Capitan or Bridalveil Fall in favor of the other, and other times including both.
And beyond subject choice are decisions like the amount of sky versus foreground to include, horizontal or vertical orientation, wide or tight focal length, polarizer orientation, motion blur in the water, and on and on. All of these choices depend on the conditions, and the way they’re handled can make or break an image.
My Yosemite Winter Moon photo workshops are timed to coincide with a full moon rising above Yosemite Valley at sunset, as well as (fingers crossed) fresh snowfall in Yosemite Valley. Yosemite Valley is the workshop’s known, static commodity; snow and the moon are its dynamic variables. While getting fresh snow is a complete a roll of the dice when scheduling a workshop a year or more in advance, the moon’s phase and position can be predicted with surgical accuracy. But there’s no such thing as a free lunch in photography, so even though I know where to be and when to be there for the moon, I still have to sweat the clouds—especially in winter.
Which is exactly what I did in this month’s workshop. Having billed this as a “winter moon” workshop, I took my students out to a view of Half Dome that aligned perfectly with the first of my three planned sunset moonrises, then watched and waited while Half Dome played games with the clouds and never came out completely. The moon? Not even close. If you read last week’s blog, you know that we finally had a moonrise success on our third and final try. But it’s what happened on the evening in between that stands out most in my memory.
In a static world, for our second sunset I’d have been at another location beside the Merced River, waiting for the moon to crest Half Dome. Because watching the moon rise above Half Dome at sunset is something I hate missing, even when there are lots of clouds, my usual approach is to lean into the moonrise despite the low odds—you just never know when the sky might open and surprise you by revealing the moon (see last week’s blog). But as the time to make the call on our sunset location approached, I could see that the east side of the valley, including Half Dome, appeared hopelessly engulfed by clouds, while the sky on the west side looked much more open. So I reluctantly (and uncharacteristically) pulled the plug on the moonrise and detoured to Valley View for sunset, hoping I wouldn’t regret it.
At Valley View, I instantly saw that the cloud swallowing Half Dome was a blooming cumulus monster that showed no hint of retreating. My decision to blow off the moonrise (somewhat) vindicated, I got my group settled in. While fairly confident we’d get something better than my Plan A Half Dome spot, I didn’t have especially high expectations for anything spectacular.
Pulling out my Sony α1 body, I surveyed the scene. Normally I start at Valley View with my Sony 24-105 f/4 G lens, but with such a nice sky this evening, I reached straight for my Sony 16-35 f/2.8 GM lens.
I see clouds like this one all the time at the Grand Canyon, but rarely in Yosemite—maybe way in the distance, but rarely this close. It only took two frames to realize the 16-35 still wasn’t wide enough, so I returned to my bag for my Sony 12-24 f/2.8 GM lens. Maybe I’ve used this lens at Valley View before, but it’s usually reserved for Yosemite’s closer El Capitan views.
When the cloud lit up and started glowing pink, its reflection switched on too, suddenly making that the scene’s most compelling element. There aren’t many situations where I’d photograph here ultra-wide and vertical, but this time I instantly knew that’s what the scene called for, even if that meant shrinking Valley View’s usually unrivaled landscape features. With my 12 – 24 oriented vertically, not only could I include all of Valley View’s primary static features (El Capitan, Bridalveil Fall, Cathedral Rocks), I could also fit the towering pink cloud and its reflection, top to bottom. To avoid including any of the sticks and leaves at my feet, I dropped lower and moved most of my tripod into the shallow water.
This evening’s show was as brief as it was spectacular. If there’s one takeaway, it’s the reminder the most successful landscape images start with finding a combination of Nature’s static and dynamic elements—identifying a location you want to photograph (static), and figuring out when to be there for the best light, color, sky, or whatever (dynamic). But your job isn’t done until you’ve identified what’s working at that moment, and put it into a composition that does the moment justice.

Large or small, crescent or full, I love photographing the moon rising above Yosemite. I truly believe it’s one of the most beautiful sights on Earth. The moon’s alignment with Yosemite Valley changes from month-to-month, with my favorite full moon alignment coming in the short-day months near the winter solstice when it rises between El Capitan and Half Dome (from Tunnel View), but I have a plan for each season. Some years the position and timing are better than others, but when everything clicks, I do my best to be there. And if I’m going to be there anyway, why not schedule a workshop? (He asked rhetorically.)
Strike one, strike two
For last week’s Yosemite Winter Moon photo workshop, I’d planned three moonrises, from three increasingly distant vantage points. On our first night, despite the cloudy vestiges of a departing storm, I got the group in position for a moonrise at a favorite Merced River sunset spot, hoping the promised clearing would arrive before the moon. The main feature here is Half Dome, but the clouds had other ideas. Though they eventually relented just enough to reveal Half Dome’s ethereal outline and prevent the shoot from being a complete loss, the moon never appeared. Strike one.
With a better forecast for the second evening, we headed into the park that afternoon with high hopes. But as the sun dropped, the clouds thickened to the point where not only did I fear we’d miss the moon again, I was pretty sure Half Dome would be a no-show as well. So I completely aborted the moonrise shoot and opted for sunset at Valley View, where El Capitan and freshly recharged Bridalveil Fall were on their best behavior. The result was a spectacular sunset that made me look like a genius (phew), but still no moon. Strike two.
Revisiting nature photography’s 3 P’s
Because the right mindset is such an important part of successful photography, many years ago I identified three essential qualities that I call the 3 P’s of Nature Photography:
- Preparation is (among many things) your foundation; it’s the research you do that gets you in the right place at the right time, the mastery of your camera and exposure variables that allow you to wring the most from the moment, and the creative vision, refined by years of experience, and conscious out-side-the-box thinking.
- Persistence is patience with a dash of stubbornness. It’s what keeps you going back when the first, second, or hundredth attempt has been thwarted by unexpected light, weather, or a host of other frustrations, and keeps you out there long after any sane person would have given up.
- Pain is the willingness to suffer for your craft. I’m not suggesting that you risk your life for the sake of a coveted capture, but you do need to be able to ignore the tug of a warm fire, full stomach, sound sleep, and dry clothes, because the unfortunate truth is that the best photographs almost always seem to happen when most of the world would rather be inside.
Most successful images require one or more of these three essential elements. Chasing the moon last week in frigid, sometimes wet, Yosemite got me thinking about the 3 P’s again, and how their application led to a (spoiler alert) success on our third and final moonrise opportunity.
Meanwhile…
As we drove into the Tunnel View parking lot, about 45 minutes before sunset, our chances for the moon looked excellent. There were a few clouds overhead, with more hanging low on the eastern horizon behind Half Dome, but nothing too ominous. My preparation (there’s one) had told me that the moon this evening would appear from behind El Capitan’s diagonal shoulder, about halfway up the face, and that area of the sky was perfectly clear. So far so good.
Organizing my group along the Tunnel View wall, I pointed out where the moon would appear, and reminded them of the previously covered exposure technique for capturing a daylight-bright moon above a darkening landscape. Eventually I set up my own tripod and Sony a7R IV, with my Sony 200 – 600 G lens with the 2X Teleconverter pointed at ground 0. In my pocket was my Sony 24 – 105 G lens, which I planned to switch to as soon as the moon separated from El Capitan. Then we all just bundled up against the elements and enjoyed the view, waiting for the real show…
But, as if summoned by some sinister force determined to frustrate me, the seemingly benign clouds hailed reinforcements that expanded and thickened right before our eyes. Their first victim was Half Dome, and it looked like they’d set their sights on El Capitan next. By the time sunset rolled around, my optimism had dropped from a solid 9 to a wavering 2. I knew the moon was up somewhere behind the curtain and tried to stay positive, but let everyone know that our chances for actually seeing it were no longer very good. I reminded them not to get so locked in on waiting for the moon that they miss out on the beauty happening right now. Ever the optimist, I switched to my 24-105, privately rationalizing that even without the moon, we’d had so much spectacular non-moon photography already, nobody could be unhappy. But still…
At that point it would have been easy to cut our losses, come in out of the cold (pain), and head to dinner. But I have enough experience with Yosemite to know that it’s full of surprises, and never to go all-in on it’s next move. So we stayed. And our persistence (we’ve checked all three now) was rewarded when, seemingly out of nowhere, a hole opened in the clouds and there was the moon. The next 10 minutes were a blur of frantic clicking and excited exclamation as my group enjoyed this gift we’d all just about given up on.
A few full moon photography tips
- Sun and moon rise/set times always assume a flat horizon, which means the sun usually disappears behind the local terrain before the “official” sunset, while the moon appears after moonrise. When that happens, there’s usually not enough light to capture landscape detail in the moon and landscape, always my goal. To capture the entire scene with a single click (no image blending), I usually try to photograph the rising full moon on the day before it’s full, when the nearly full (99% or so illuminated) moon rises before the landscape has darkened significantly.
- The moon’s size in an image is determined by the focal length—the longer the lens, the larger the moon appears. Photographing a large moon above a particular subject requires not only the correct alignment, it also requires distance from the subject—the farther back your position, the longer the lens you can use without cutting your landscape subject.
- To capture detail in a rising full moon and the landscape (in a single click), increase the exposure until the highlight alert appears on your LCD (any more exposure blows out the moon). At that point, you can’t increase the exposure any more, even though the landscape is darkening. You’ll be amazed by how much useable data you’ll be able to pull from the in nearly black shadows in Lightroom/Photoshop (or whatever your processing software). In the image I share above, my LCD looked nearly black except for the single white dot of moon. Eventually the scene will become too dark—exactly when that happens depends on your camera, but if you’re careful, you can keep shooting until at least 15 minutes after sunset.

I’m in Yosemite for a workshop so my blogging time is significantly curtailed, but let’s see what happens…
Photography is the futile attempt to render a three dimensional world in a two dimensional medium. It’s “futile” because including actual depth in a photograph is literally impossible. But impossible doesn’t mean hopeless. One of the simplest things photographers can do to elevate their images is think about their scene in three dimensions, specifically how to create the illusion of depth by composing elements at multiple distances from the camera.
Many photographers miss opportunities by simply settling for the beautiful scene before them instead of looking for ways to make it even better. A more productive approach is to start with the beautiful aspect of the scene you want to emphasize (brilliant sunset, backlit flower, towering peak, vivid rainbow, plunging waterfall, whatever), then aggressively seek an object or objects nearer or farther to complement it. Of course that’s sometimes easier said than done, but this near/middle/far mindset should be present for every capture.
Thinking foreground and background is a great start, but merely having objects at varying distances isn’t always enough—you also need to be aware of how those objects guide your viewer’s eye through the frame. We hear a lot of photographers talk about using “leading lines” to move the eye, but a line doesn’t need to be a literal (visible) line to move the eye, because viewers will subconsciously connect objects to create virtual lines.
To help me achieve virtual lines that move the eye, I think in terms of “visual weight”: a quality of an object that tugs the eye like gravity, subconsciously pulling the viewer’s gaze in its direction. These qualities include, among other things: mass, shape, brightness, contrast, color, texture, and sometimes just position in the frame. A single one of these qualities can give an object visual weight, but combining then can be even more effective.
Additionally, an object’s emotional power can boost its visual weight. For example, a small moon can pull the eye more than a larger bright cloud, and Half Dome has more visual weight than a random rock occupying the same amount of frame real estate.
With my primary subject and complementary (eye moving) objects identified, I still need to consider the linear connection between these visual components. I like diagonal relationships because of the visual tension created by moving the eye along multiple planes. While creating these virtual diagonals requires careful positioning, it’s surprising how many photographers just remain planted with their tripod as if it has grown roots—either they don’t see the benefit of repositioning, or don’t think moving is worth the effort.
Whatever the reason, it’s important for photographers to understand the power of shifting position to control foreground and background relationships: move left and your foreground shifts right relative to the background; move right and the foreground shifts left relative to the background. Either way, the closer the foreground is relative to the background, the more dramatic the shift. And contrary to what you might believe, it’s impossible to change foreground/background perspective with focal length—to change perspective, you must change position: forward/backward, left/right, up/down.
An often overlooked shift that can be quite powerful is up/down. Often I’m able to un-merge objects at different distances by simply raising my tripod or climbing atop a nearby rock. Dropping low will emphasize the closest elements, and when my frame has a large and boring empty space (such as a field of weeds or dirt) between the foreground and background, I drop lower to shrink that gap.
It’s taken me a while to figure out the best way to convey these concepts to my photo workshop students. In most workshops, I find that many of the students haven’t picked up their cameras in weeks or months (or years!), so I’ve learned give them time to get back in their creative zone before laying all this stuff on them.
For example, in my Yosemite workshops I usually start with the classic shots that probably drew them to the park in the first place, places like Tunnel View and Valley View, where there are obvious compositions that lead to easy success. At the first image review I give a little talk on composition and moving the eye (among other things), then everyone shares images and I offer my feedback.
By the second day, armed with that foundation and a little Day 1 success, they’re usually ready to challenge their creativity and attack the less heralded spots whose beauty is more subtle. This growth is obvious as soon as the Day 2 image review. I’m frequently blown away by how quickly they’ve refined their inherent creative vision well enough to see beyond the obvious and find compositions that are both beautiful and unique.
One autumn favorite creative spot is the section of the Merced River from the Pohono Bridge upstream to Fern Spring, and even a little beyond. Fern Spring alone, with its stair-step cascades and a small reflecting pool that’s covered with color each fall, has enough to occupy a creative photographer for hours. And just across the road is a trail that skirts the river and traverses a forest filled with colorful maple and dogwood trees. The entire area is chock-full of creative opportunities that include whitewater, still water reflections, and of course (lots of) fall color.
In last month’s Fall Color and Reflections workshop, once I was satisfied that everyone was comfortable with their cameras and starting to trust their creative instincts, I took them to Fern Spring. Once there, I gave them the lay of the land and encouraged them to explore. Early in the workshop my groups tend to stick close to me, but this afternoon I was encouraged to see everyone instantly scatter. That’s always a good sign that they’re starting to get in the zone—even though it means I need to chase each one down to make sure they’re doing okay.
By the time I’d finished my rounds and confirmed that each person had things under control (and fearing that my presence might actually be a distraction), I was left with about 20 minutes to do a little shooting of my own. I quickly grabbed my camera and beelined upstream to a spot that I can’t take a group to because there’s no room for more than one person, no trail to get there, and it’s frighteningly easy to fall in the river. (I’ve had a couple of minor mishaps here that required changing shoes and socks, and maybe spending a couple of hours in pants wet to my calf, but was always grateful it wasn’t worse).
Rather than a standard fall color location, this is a fallen color spot that accumulates leaves that have drifted downstream from elsewhere to float among the rocks. Each year, the quality of the floating color varies from none to lots—not enough water and the leaves don’t make it into the rocks; too much water and the leaves just wash right by to locations downstream.
I was happy to confirm that this was indeed a good year for the floating color. Being in a hurry, I could have very easily snapped off a couple of frames from where I stood and called it good. But often the difference between an image that’s merely a decently executed rendering of a beautiful scene, and an image that stands out for the (often missed) aspects of the natural world it reveals, is the time it takes to identify and connect the scene’s visual relationships. So I took just a little more time to align the elements.
In this case that meant positioning myself so the foreground rocks and leaves aligned with the middle-ground rocks and reflection, which aligned with cloud-shrouded El Capitan in the background. Words cannot express how awkward this position was, requiring a grand total of 5 splayed legs—3 tripod and 2 human. But still it wasn’t quite right—until I dropped my tripod down to about a foot above the water to make the leaves more prominent.
After setting my exposure, I focused on the third small foreground rock, then dialed my polarizer to reduce the reflection on the leaves while retaining the upstream reflection. Click.

Autumn Leaves on the Rocks, Valley View Reflection, Yosemite

It’s easy to be overwhelmed at the first sight of a location you’ve longed to visit for years. And since by the time you make it there you’ve likely seen so many others’ images of the scene, it’s understandable that your perception of how the scene should be photographed might be fixed. But is that really the best way to photograph it?
Valley View in Yosemite is one of those hyper-familiar scenes. El Capitan, Bridalveil Fall, and Cathedral Rocks pretty much slap you in the face the instant you land at Valley View, making it easy to miss all the other great stuff here. This month’s workshop group visited Valley View twice, with each visit in completely different conditions, which got me thinking about about the number of ways there are to photograph most scenes, and how it’s easy to miss opportunities if you simply concentrate on the obvious. Most scenes, familiar or not, require scrutiny to determine where the best images are—on every visit.
Sunrise Reflection, El Capitan, Yosemite
On our first visit, Bridalveil Fall was just a trickle lost in deep shadow, so I focused my attention on El Capitan, opting for a vertical frame to emphasize El Cap, the beautiful clouds overhead, and the reflection. When we returned a couple of days later, Bridalveil had been recharged by a recent rain, the soft light was more even throughout the scene, and patches of fallen leaves and pine needles now floated atop the reflection. All this called for a completely different approach.
On this return visit, since I thought there was (just barely) enough water in Bridalveil to justify its inclusion, I went with a horizontal composition. It would have been easy to frame up El Capitan, Bridalveil, and Cathedral Rocks, throw in a little reflection and call it good. But (as my workshop students will confirm) I obsess about clean borders because I think they’re the easiest place for distractions to hide.
So before every click, I do a little “border patrol,” a simple reminder to deal with small distractions on my frame’s perimeter that can have a disproportionately large impact on the entire image. (I’d love to say that I coined the term in this context, but I think I got it from fellow photographer and friend Brenda Tharp—not sure where Brenda picked it up.)
To understand the importance of securing your borders, it’s important to understand that our goal as photographers is to create an image that not only invites viewers to enter, but also persuades them to stay. And the surest way to keep viewers in your image is to help them forget the world outside the frame. Lots of factors go into crafting an inviting, persuasive image—things like compositional balance, visual motion, and relationships are all essential (and topics for another day), but nothing reminds a viewer of the world outside the frame more than an object jutting in or cut off at the edge.
When an object juts in on the edge of a frame, it often feels like part of a different scene is photobombing the image. Likewise, when an object is cut off on the edge of the frame, it can feel like part of the scene is missing. Either way, it’s a subconscious and often jarring reminder of the world beyond the frame. Not only does this “rule” apply to obvious terrestrial objects like rocks and branches, it applies equally to clouds.
And there are other potential problems on the edge of an image. Simply having something with lots of visual weight—an object with enough bulk, brightness, contrast, or anything else that pulls the eye—on the edge of the frame can throw off the balance and compete with the primary subject for the viewer’s attention.
Of course it’s often (usually?) impossible to avoid cutting something off on the edge of the frame, so the next best thing is to cut it boldly rather than to simply trim it. I find that when I do this, it feels intentional and less like a mistake that I simply missed. And often, these strongly cut border objects serve as framing elements that hold the eye in the frame.
To avoid these distractions, I remind myself of “border patrol” and slowly run my eyes around the perimeter of the frame. Sometimes border patrol is easy—a simple scene with just a small handful of objects to organize, all conveniently grouped toward the center, usually requires minimal border management. But more often than not we’re dealing with complex scenes containing multiple objects scattered throughout and beyond the frame. Even when you can’t avoid cutting things off, border patrol makes those choices conscious instead of random, which is almost aways better.
As nice as the Valley View reflection was on this visit, it was sharing space with a disorganized mess of rocks, driftwood, and leaves. Organizing it all into something coherent was impossible, but I at least wanted to have prominent color in my foreground and take care to avoid objects on the edge of my frame that would pull viewers’ eyes away from the scene.
Unfortunately, as I used to tell my kids all the time (they’re grown and no longer listen to me), you can’t always have what you want. In this case, including the best foreground color also meant including an unsightly jumble of wood, rock, and pine needles in the lower right corner. But after trying a lot of different things, I decided this was the best solution—especially since I managed to find a position and focal length that gave me completely clean borders everywhere else in my frame.
I very consciously included enough of the mass in the lower right that it became something of a boundary for that corner of the image (not great, but the best solution possible). I also was very careful to keep an eye on the ever-changing clouds. The light on El Capitan that broke through just as I had my composition worked out felt like a small gift.

It amuses (and frustrates) me when photographers guard their information like state secrets. Photography isn’t a competition, and I’ve always felt that the more photographers can foster a sense of community, the more everyone benefits. (I will, however, protect locations at risk of being damaged by too much attention.) With that in mind, I’m sharing below some of the photography insights I’ve learned from a lifetime of Yosemite visits, and encourage you to share your own insights, wherever and whatever they may be, when the opportunity arises.
Yosemite FAQs
I get asked all the time, what’s the best season to be in Yosemite? For many reasons, including the fact that everyone defines “best” differently, that’s an impossible question to answer. So instead I try to identify the pros and cons of each season in Yosemite and let the questioners decide for themselves what sounds best to them.
- Winter: Because the crowds have vacated, Yosemite is at its most peaceful in winter. And it’s never more beautiful than when smothered with fresh snow, but in the relatively warm temperatures of Yosemite Valley, snowstorms only happen a few times each winter so I try to time my visits so I can be there during a storm.
- Spring: With its booming waterfalls, vivid greens, mirror-like vernal pools, and ubiquitous dogwood blooms (okay, so technically they’re bracts), spring is classic postcard Yosemite. Spring is also when the crowds return.
- Summer: For tourists only—but if you find yourself in Yosemite on a crowded (understatement) summer day, rising at the first sign of pre-sunrise light will give you at least a couple of hours of glorious peace.
- Autumn: By autumn the crowds have left, and while Yosemite’s waterfalls have fallen silent, the low and slow water turns the Merced River into a reflecting ribbon that splits Yosemite Valley. The resulting mirror reflections of granite monoliths mingling with the season’s red and gold are one of my favorite things to photograph in Yosemite.
Another question I get asked a lot is some version of, “Where in Yosemite should I photograph sunrise/sunset.” Again there’s no absolute answer, so I just try to provide enough information for the questioners to make their own decisions.
- Sunrise: Yosemite is not an inherently good sunrise location. In fact, on a typical California clear sky morning, it’s pretty lousy. That’s because most of Yosemite Valley’s best views face east, toward shaded subjects against the brightest part of the sky. Clouds flip the equation, subduing the bright sky and (fingers crossed) filling it with color. But even the cloudless days aren’t an excuse to stay in bed. On these days try to be in position for the first light on El Capitan, about 15/20 minutes after the “official” (flat horizon) sunrise. And in winter Yosemite Falls also gets beautiful morning light.
- Sunset: Even without clouds, Half Dome gets nice sunset light year-round. In the long-night months (from the autumnal equinox to the vernal equinox) so does El Capitan. In the long-day months (from the vernal equinox to the autumnal equinox), the late light goes to Cathedral Rocks and Bridalveil Fall.
Send in the clouds
Regardless of the season, clouds change everything, especially when storm clouds that swirl about Yosemite’s monoliths. Even high or thin clouds can be difference makers that paint the usually boring sky with color and (if you’re lucky) reflect in foreground water.
Unfortunately, storm clouds often drop all the way to the valley floor, obscuring all the features you traveled to photograph. Rather than giving up, my approach to stormy weather in Yosemite is to wait it out. A clearing storm is the Holy Grail of Yosemite photography, an experience that never gets old, no matter how many times it’s witnessed. And when I say wait it out, I don’t mean just returning to your room and looking outside every once in a while, I mean circling the valley in your car, or parking somewhere with an eye on the sky. Tunnel View is a great spot for this.
My other tip for photographing a clearing storm in Yosemite is not staying in one place too long. If you wait until it’s not beautiful anymore before moving on, you won’t leave until the show’s over everywhere—instead, remind yourself that it’s just as beautiful everywhere else, and move on when you find yourself repeating compositions.
Reflecting on reflections
Regardless of the location or conditions, a reflection can turn an ordinary pretty picture into something special. That’s especially true in Yosemite. Yosemite’s reflection spots change with the season: in spring, they’re best in the vernal pools that form in the meadows, and a small handful of Merced River spots, where it widens (like Swinging Bridge) or pools near the river’s edge; in autumn (and late summer), pretty much the entire Merced River is a mirror. Winter Merced River reflections can be nice too, depending on the weather and amount of runoff.
A lifetime of Yosemite visits helps me pursue its reflections. But even if you don’t know the spots for Yosemite reflections, they’re not hard to find if you keep your eyes open.
The most frequent reflection mistake I see is photographers walking past a reflection because it doesn’t contain an interesting subject. Maximizing reflection opportunities starts with understanding that, just like a billiard ball striking a cushion, a reflection always bounces off the reflective surface at exactly the same angle at which it arrived.
Armed with this knowledge, when I encounter any reflective surface, I scan the area for a reflection-worthy subject and position myself to intercept my target subject’s reflected rays, moving left/right, forward/backward, up/down until my reflection appears. Another important aspect of reflection management is juxtaposing the reflection with submerged or exposed objects in the water.
Putting it all together
These cloud and reflection factors aligned for me in last week’s Yosemite Fall Color and Reflections workshop. Based on the weather forecast when we wrapped up the previous night, I gathered the group early enough for our sunrise departure to swing into Tunnel View for quick survey of Yosemite Valley. If there had been no clouds, clearing storm clouds, or zero-visibility clouds, we’d have stayed there. But when I saw a nice mix of high to mid-clouds, I went with Plan-B and beelined to Valley View.
We arrived more than 30 minutes before sunrise and I was pleased to see only one other car in the parking lot. I’d already brought my group here once, so everyone already had an idea of what they wanted to do—a few went just upstream from the cars to the nice reflection of Cathedral Rocks and Bridalveil Fall; the rest made their way out to the new-ish (last couple of years) and quite conveniently placed logjam that provides a perspective of El Capitan that previously would have required walking on water to achieve.
I left my gear in the car, moving back and forth between the two cohorts and and monitoring the sky. I’ve photographed here so much, I had no plan to this morning, but when the clouds overhead started to pink up, I couldn’t resist. Rather than grabbing my entire camera bag, I just pulled out my tripod and Sony a7R IV with the Sony 24-105 f/4 G lens already attached and trotted down to the natural platform formed by the log jam.
I knew I didn’t have much time, so I quickly found a spot where, by dropping my tripod a little, I could frame El Capitan’s reflection with several of the many protruding rocks. Since Bridalveil Fall wasn’t flowing very strongly, and the light on El Capitan was better, I went with a vertical composition that featured El Capitan only.
The pink was so intense that for a minute or so, it slightly colored the rocks. Before the color faded, I managed to capture several frames with this composition, each with a slightly different polarizer orientation, but I ended up choosing the one that maximized the reflection.

I’ve spent the last week moving, and with my annual Grand Canyon Raft Trip for Photographers launching Tuesday, I haven’t had a lot of time for blogging (and much else). But I’m still committed to posting a new blog each week, so I’m sharing a new image from one of this spring’s Yosemite workshops, and a brief description of its capture. I also dusted off and polished up the Rainbow article from my Photo Tips tab. I’ll be off the grid until May 31, so next week’s post will likely be a little late.
It’s become a tradition to kick off my Yosemite spring workshops with a rainbow on Bridalveil Fall. Though the timing varies with the date, I’ve done it enough to narrow the rainbow’s start down to about a 2 minute window for whatever date I’m there. Not only is this little dash of rainbow a thrilling spectacle and beautiful introduction to Yosemite, it also creates an (unjustified) illusion of genius for the workshop leader.
With rain and maybe even a little snow, this year’s weather forecast for our first day looked great in many ways, but not so much for rainbows. But rainbow or not, Tunnel View is a great spot to start a workshop because it’s the most complete view of all things Yosemite. It’s also the first place Yosemite’s storms clear, so even without sunlight something special might be in store.
The storm was just starting to clear when we arrived and I almost got trampled as my group raced to set up. Between the swirling clouds and Half Dome’s appearance (not always a sure thing during a Yosemite clearing storm), things were already going pretty well when shafts of light broke through to illuminate random parts of the valley and surrounding granite.
I checked my watch and crossed my fingers when I realized that we’d be able to add a rainbow to Bridalveil if the light were to make it there. A couple of minutes later Leaning Tower (the diagonal just to the right of the fall) lit up, and a few seconds later a small patch of light hit the evergreens in front of the fall.
After telling everyone what was about to happen, I set up my composition and said a little prayer that the light would cooperate. The patches of light quickly expanded and merged and there it was. I often shoot this rainbow with a telephoto because the sky is so often blank blue, but the whole scene was so beautiful this afternoon that I went with my Sony 24-105 G lens on my (brand new!) Sony a1.
This was the very first time I’d used this camera, and while I thought I’d set it up to match my Sony a7RIV, I soon discovered that I’d missed a few things. For example, I usually shoot in single shot mode, but my a1 was in fast continuous mode, an oversight that became apparent when my first shutter press (slow and gentle, as always) fired off 6 identical frames before I released my finger. My goodness is this camera fast.
I have so many images of this rainbow that I only photographed it for a couple of minutes—just long enough to be confident that I’d captured something I didn’t have. When I finished shooting I just stood back to watch the rainbow move up the fall—and to listen to the exclamations of marvel from the group.
Fortunately none of my settings oversights were a major hindrance and were quickly corrected. Since that afternoon I’ve used my a1 enough to know that I’m going to love using it, and can’t wait to try it out in the Grand Canyon this week.
Read on to learn about rainbows, how to anticipate them, and how to photograph them…
All About Rainbows
Let there be light
Most people understand that a rainbow is light spread into various colors by airborne water drops. Though a rainbow can feel like a random, unpredictable phenomenon, the natural laws governing rainbow are actually quite specific and predictable, and understanding these laws can help photographers anticipate a rainbow and enhance its capture.
The sun’s visible wavelengths are captured by our eyes and interpreted by our brain. When our eyes take in light comprised of the full range of visible wavelengths, we perceive it as white (colorless) light. Color registers when some wavelengths are more prevalent than others. For example, when light strikes an opaque (solid) object such as a tree or rock, some of its wavelengths are absorbed; the wavelengths not absorbed are scattered (reflected). Our eyes capture this scattered light, send the information to our brains, which interprets it as a color. When light strikes water, some is absorbed, some passes through to reveal the submerged world, and some light is reflected by the surface as a reflection.
Light traveling from one medium to another (e.g., from air into water) refracts (bends). Different wavelengths refract different amounts, causing the light to split into its component colors.
To understand the interaction of water and light that creates a rainbow, it’s simplest to visualize what happens when sunlight strikes a single drop. Light entering a water drop slows and bends, with the shorter wavelengths bending more than the longer wavelengths: refraction. Refraction separates the originally homogeneous white light into the myriad colors of the spectrum: red, orange, yellow, green, blue, indigo, violet (in that order).
But simply separating the light into its component colors isn’t enough to create a rainbow. Actually seeing the rainbow spectrum caused by refracted light requires that the refracted light be reflected back to our eyes somehow.
A raindrop isn’t flat like a sheet of paper, it’s spherical, like a ball. Light that was refracted when it entered the front of the raindrop, continues through to the back of the raindrop, where some is reflected. To view a rainbow, our eyes must be in the correct position to catch this reflected spectrum of color—fortunately, this angle is very consistent and predictable.
Red light reflects at 42 degrees, violet light reflects at 40 degrees, while the other spectral colors reflect back between 42 and 40 degrees. That’s why the top color of the primary rainbow is always red, the longest visible wavelength; the bottom color is always violet, the shortest visible wavelength.
Follow your shadow
Every raindrop struck by sunlight creates a rainbow somewhere. But just as the reflection of a mountain peak on the surface of a lake is visible only when viewed from the angle the reflection bounces off the lake’s surface, a rainbow is visible only when you’re aligned with the 42 – 40 degree angle at which the raindrop reflects light’s refracted spectrum of rainbow colors.
Lucky for most of us, viewing a rainbow requires no knowledge of advanced geometry. To locate or anticipate a rainbow, put your back to the sun and picture an imaginary line originating at the sun, entering the back of your head, exiting between your eyes, and continuing into the landscape in front of you—this line points to the “anti-solar point,” an imaginary point exactly opposite the sun from your viewing position.
It helps to remember that your shadow always points toward the anti-solar point—and toward the center of the rainbow, which forms a 42 degree circle around the line connecting the sun and the anti-solar point. Unless we’re in an airplane or atop a mountain peak, we don’t usually see the entire circle because the horizon gets in the way. So when you find yourself in a mixture sunlight and rain, locating a rainbow is as simple as following your shadow and looking skyward—if there’s no rainbow, the sun’s probably too high.
High or low
Sometimes a rainbow appears as a majestic half-circle, arcing high above the distant terrain; other times it’s merely a small arc hugging the horizon. As with the direction of the rainbow, there’s nothing mysterious about its varying height. Remember, every rainbow would form a full circle if the horizon didn’t get in the way, so the amount of the rainbow’s circle you see (and therefore its height) depends on where the rainbow’s arc intersects the horizon.
While the center of the rainbow is always in the direction of the anti-solar point, the height of the rainbow is determined by the height of the anti-solar point, which will always be exactly the same number of degrees below the horizon as the sun is above the horizon. It helps to imagine the line connecting the sun and the anti-solar point as a fulcrum, with you as the pivot—picture yourself in the center of a teeter-totter: as one seat rises above you, the other drops below you. That means the lower the sun, the more of the rainbow’s circle you see and the higher it appears above the horizon; conversely, the higher the sun, the less of the rainbow’s circle is above the horizon and the flatter (and lower) the rainbow appears.
Assuming a flat, unobstructed scene (such as the ocean), when the sun is on the horizon, so is the anti-solar point (in the opposite direction), and half of the rainbow’s 360 degree circumference will be visible. But as the sun rises, the anti-solar point drops—when the sun is more than 42 degrees above the horizon, the anti-solar point is more than 42 degrees below the horizon, and the only way you’ll see a rainbow is from a perspective above the surrounding landscape (such as on a mountaintop or on a canyon rim).
Of course landscapes are rarely flat. Viewing a scene from above, such as from atop Mauna Kea in Hawaii or from the rim of the Grand Canyon, can reveal more than half of the rainbow’s circle. From an airplane, with the sun directly above you, all of the rainbow’s circle can be seen, with the plane’s shadow in the middle.
Double Your pleasure
Not all of the light careening about a raindrop goes into forming the primary rainbow. Some of the light slips out the back of the raindrop to illuminate the sky, and some is reflected inside the raindrop a second time. The refracted light that reflects a second time before exiting creates a secondary, fainter rainbow skewed 50 degrees from the anti-solar point. Since this is a reflection of a reflection, the colors of the secondary rainbow are reversed from the primary rainbow.
And if the sky between the primary and secondary rainbows appears darker than the surrounding sky, you’ve found “Alexander’s band.” It’s caused by all the light machinations I just described—instead of all the sunlight simply passing through the raindrops to illuminate the sky, some of the light was intercepted, refracted, and reflected by the raindrops to form our two rainbows, leaving less light for the sky between the rainbows.
Waterfalls are easy
Understanding the optics of a rainbow has practical applications for photographers. Not only does it help you anticipate a rainbow before it happens, it also enables you to find rainbows in waterfalls.
A rainbow caused by sunlight on rain can feel random because it’s difficult to know exactly where the rain will fall, when the sun will break through, and exactly where to position yourself to capture the incongruous convergence of rainfall and sunshine. A waterfall rainbow, on the other hand, can be predicted with clock-like precision because we know exactly where the waterfall and sun are at any give time—as long as clouds don’t get in the way, the waterfall rainbow appears with clock-like precision.
Yosemite is my location of choice for waterfall rainbows, but maybe there’s a waterfall or two near you that might deliver. Just figure out when the waterfall gets direct sunlight early or late in the day, then put yourself somewhere on the line connecting the sun and the waterfall. And if you have an elevated vantage point, you’ll find that the sun doesn’t even need to be that low in the sky.
Spring in Yosemite is waterfall rainbow season, and I know exactly where to be and when to be there for both of Yosemite Valley’s major waterfalls. In fact, given the variety of vantage points for viewing each of these falls, I can usually get two or three rainbows on each fall on any given day.
In addition to clouds, there are other variables to deal with. One is the date, because the path and timing of the sun’s arc across the sky changes with each passing week. Another thing that can throw the timing off slightly is the amount of water in the fall—following a wet winter the spring runoff increases, and with it the amount of mist. Generally, the more mist, the sooner the rainbow will appear and the longer it lasts. And finally there’s wind, which spreads the mist and usually improves the rainbow by increasing its size.
While all these variables make it difficult for me share the exact schedule of Yosemite’s waterfall rainbows from the variety of vantage points, I can give you some general guidance: look for a rainbow on Yosemite Falls in the morning, and Bridalveil Fall in the afternoon. And if you don’t mind a short but steep hike, you can also find a rainbow on Vernal Fall in the afternoon.
Moonbows
Understanding rainbow optics can even help you locate rainbows that aren’t visible to the naked eye. A “moonbow” (lunar rainbow) is a rarely witnessed and breathtaking phenomenon that follows all the natural rules of a daylight rainbow. But instead of resulting from direct sunlight, a moonbow is caused by sunlight reflected by the moon.
Moonlight isn’t bright enough to fully engage the cones in your eyes that reveal color, though in bright moonlight you can see the moonbow as an arcing monochrome band. But a camera on a sturdy tripod can use its virtually unlimited shutter duration to accumulate enough light to bring out a moonbow in full living color. Armed with this knowledge, all you need to do is put yourself in the right location at the right time.
Probably the best known moonbow is the one that appears on Yosemite Falls each spring. Usually viewed from the bridge at the base of Lower Yosemite Fall, the best months are April, May, and June, with May probably being the best combination of moonlight angle and ample water.
Unfortunately, this phenomenon isn’t a secret, and the bridge can be quite crowded on spring full moon nights—in high runoff springs, it can also be extremely wet (pack your rain gear). The base of Upper Yosemite Fall can also have a moonbow when viewed from the south side of Cook’s Meadow, especially in wet springs.

Making a Scene

Think about what goes into making a landscape image. If the scenes and conditions are our raw materials, then it would be logical to say that our camera gear is our tools. But in addition to cameras, lenses, and other physical photography hardware, I’d say that our photography toolkit also includes the techniques we employ to deal with nature’s fickle whims.
And speaking of fickle whims, it’s impossible to deny that conditions make some scenes easier than others. But as much as I long for crimson sunsets, vivid rainbows, mirror reflections, and a host of other natural phenomena that can make virtually any shot feel like a slam dunk, these things are not always available when I want to make an image. For me, one of the greatest challenges is overcoming the boring (cloudless) skies that my California home is known (and loved) for. Not only do blank skies add rarely anything to a scene, they’re responsible for harsh light and the extreme dynamic range that even the best cameras struggle to handle. What’s a photographer to do?
For starters, we need to open our mind (and eyes). One of photography’s less heralded gifts is its ability, over time, to teach us to tune-in to nature’s subtleties, and how to leverage conditions that we once viewed as too difficult, into beautiful images. Fortunately, difficult doesn’t mean impossible—in fact, difficult can be downright fun. And the truth is, there are a lot of ways to overcome boring skies. Here are some suggestions:
- Shade: One of my favorite approaches to blank skies is photographing moving water, spring flowers, and fall color in full shade. While not spectacular, shade light is shadowless and easy to work with. It also makes it easy to blur water without a filter.
- Reflection: For the best reflections, look for sunlit subjects (the brighter the better) reflecting in still, shaded water.
- Sunstar: Any time the sun’s up, a sunstar is a readily available addition option for spicing up your scene. Position yourself so all but a small sliver of sun is blocked by an opaque object (such as a tree, rock, or the horizon), dial your f-stop to f/16 or smaller. Note that some lenses deliver sharper, more defined sunstars than others, and in general, wide lenses work best, especially primes and high quality zooms.
- Silhouette: Blank skies at sunrise and sunset are a great opportunity to create silhouettes that emphasize color and shape by eliminating everything in the scene except color and shape. Better still, incorporating a crescent moon (which always rises just before the sun, and sets just after the sun), can take silhouette scenes to the next level.
- Stars: Don’t forget the night sky. Often when I’m disappointed by a lack of clouds at a nice location, I just wait until dark and photograph the scene by moon- or starlight.
- Black and white and infrared: While I don’t photograph B&W and infrared, they are wonderful techniques for dealing with harsh midday light.
For example
Given their frequency, I’ve become pretty good at making the best of blue sky days in Yosemite. While last month’s Yosemite Waterfalls and Dogwood photo workshop did enjoy a few clouds, we also dealt with a fair amount of blank skies. For our first sunrise we photographed silhouettes and a rising crescent moon. And later in the workshop we spent a couple of hours photographing dogwood in the shade (mixed with a little sunlight) in the Fern Springs / Pohono Bridge area. But I think my favorite blue sky shoot came at Cathedral Beach on the workshop’s penultimate afternoon.
Cathedral Beach is an up-close view of El Capitan right on the Merced River. The low and slow flow of autumn makes a glassy reflection here, and in the months closer to the winter solstice, when the sun is farther south, all of El Capitan gets spectacular late afternoon light. But by mid-spring the river rushes and swirls with snowmelt, and the sun has moved so far north that only El Capitan’s west-facing wall gets late sunlight. But as you can see, all is not lost.
Viewing El Capitan from Cathedral Beach that afternoon, the first thing to catch my eye was the gorgeous light etching the otherwise shaded granite’s vertical plunge. No less spectacular was the brilliant backlight illuminating the cottonwood and grass across the river and reflecting color in the river.
I pulled out my (brand new!) Sony A1 and pondered my lens choice. Since capturing all of El Capitan from this location requires something wider than 24mm, I’d normally go with my Sony 16-35 GM or 12-24 GM lens here. But with no clouds and most of El Capitan in shade, I really wanted to eliminate the sky, most of the granite, and the less interesting surrounding foliage, so I reached for my Sony 24-105G lens.
This scene worked as a horizontal or vertical, but I finally zeroed in on the vertical composition because it was the best way to distill the scene down to its essentials: El Capitan’s edge light, the backlit foliage, the reflection, and the gold-flecked riverbed beneath parallel ripples. I moved along the riverbank until all this good stuff aligned with the set of grassy mounds catching light in the near foreground. I wanted front-to-back sharpness, so I stopped down to f/16 and focused on the most distant of the foreground mounds. And even though I didn’t have a mirror surface, I dialed the reflection up with my polarizer to add a little color to the river.
In Yosemite it’s hard to take a bad picture, but some are more rewarding than others. While I doubt it will be one of those images that goes viral, this image makes me especially happy because finding it and assembling all the components took a little creative effort.

More than 15 years ago I left a good job at an excellent (and very well known) tech company to pursue a career in nature photography. After all, I had a good camera and years of amateur photography experience—what could possibly go wrong? Turns out I had no interest in any of the kinds of photography that actually make money, so (in hindsight) my decision was somewhat riskier than I had imagined. But, while photography hasn’t brought me great financial fortune, I do indeed feel rich beyond all measure.
Since first picking up a serious camera in my early 20s (an Olympus OM-2, if you must know), I’d been a very content amateur photographer, able to choose my photo destinations and the images I clicked for the sheer joy they brought. Period. But, being stuck in a job that stifles your creativity tends to make you rethink life choices.
At the time I’d found myself swept up in the earliest waves of the photography renaissance spurred by digital capture. I loved the instant feedback and control it brought, and started fantasizing about a transitioning my livelihood to photography. But as I started plotting my transition, I sensed that a significant risk of turning one’s passion into a profession is making choices based on the income they generate rather than the pleasure they bring. Hoping to keep the joy in my photography, I made a personal vow to only photograph what I want to photograph, and to never take a picture just because I thought it would earn money.
To honor this commitment while still paying the bills, I blended my 20+ year career in technical communications (tech writing, training, and support) with my years of photography experience and subject knowledge, to create a photography business based on photo workshops rather than image sales. (Of course I do sell images too, but because I’ve always viewed image sales as a bonus rather than something to something I rely on, I’ve been able to honor my commitment to only take pictures that make me happy.) And here I am.
I’m thinking about this right now because sometimes I’ll come across an image that reminds me how lucky I was to have been at these places when I would have otherwise been fighting traffic or imprisoned in a cubicle. I found today’s image while engaged in one of my favorite idle time exercises: Start with a favorite image, return to the folder for that trip, and look for unprocessed images captured in the conditions of that day. This time, overdue for a blog post, I didn’t go too far back, ending up revisiting my images from the snowy opening day of last year’s December Yosemite Winter Moon workshop.
Given how happy the previously shared images from this day make me, this choice was low hanging fruit, but I’m actually a little surprised to have found something I like as much as, or more than, what I already had.
When I’m in the park by myself I tend to avoid from the popular spots. But these spots are popular for a reason, and since this was the workshop’s first day, I wanted to give my group a chance to photograph the iconic scenes in the best conditions. Granted (speaking of low hanging fruit), Valley View is one of those spots that really doesn’t need help to be beautiful, so adding fresh snow almost seems unfair. But after a lifetime of visiting Yosemite, I can honestly say that it doesn’t get much better than this, and it was a treat to be able to share that beauty with an appreciative group. The fact that this was the first view of Yosemite for some (but I didn’t have the heart to tell them it’s not always like this) made it even more memorable for me.
For this composition I used the snow-capped rocks to add a little foreground interest. They’d have been pretty hard to avoid anyway, but I was very conscious of where I set up my tripod to control where the rocks landed in my scene—not too close to the borders, and not merged with the important parts of the reflection.
In addition to the snow, the clouds this afternoon were truly special—not only the swirling fragments between El Capitan and Cathedral Rocks, but also the column that appears to be tumbling down El Capitan like a waterfall. Just another day at the office….
