Just when you start getting cocky, nature has a way of putting you back in your place. Case in point: last week’s full moon, which my workshop group photographed to great satisfaction from the side of Turtleback Dome, near the road just above the Wawona Tunnel.
I love photographing the moon, in all of its phases for sure, but especially in its full and crescent phases, when it hangs on the horizon in nature’s best light. I’ve developed a method that allows me to pretty much nail the time and location of the moon’s appearance from any location, and love sharing the moment with my workshop students. (Because my workflow has been in place for about ten years, I don’t use any of the excellent new software tools that automate the moon plotting process.)
Last week’s workshop was no exception, and after much plotting and re-plotting, I decided that rather than my usual Tunnel View vantage point, the view just west of the Wawona Tunnel would work better for this November’s full moon. Arriving about 30 minutes before “showtime,” I gathered everyone around and pointed a spot on Half Dome’s right side, about a third of the way above the tree-lined ridge, and told them the moon would appear right there between 4:45 and 4:50.
Sure enough, right at 4:47 there it was and I exhaled. We photographed the moon’s rise for about 30 minutes, until difference between the darkening valley and daylight-bright moon became too great for our cameras to capture lunar detail. Everyone was thrilled, and I was an instant genius—I believe I even heard “moon whisperer” on a few lips.
The workshop wrapped up the next evening, and I was still basking in my new-found moon whisperer status as I drove home down the Merced River Canyon with my daughter Ashley in the passenger seat. In a car behind us was workshop participant Laurie, who had never been down that road and wanted to follow me to the freeway in Merced.
Hungry, we stopped at one of my favorite spots, Yosemite Bug Rustic Mountain Resort in Midpines (check it out), for dinner. About an hour later, our stomachs full, we were walking back to the cars when someone pointed to a glow atop the mountain ridge above the resort. Ashley and I recognized it as the rising moon, but since this wasn’t a full disk, immediately entered into a friendly debate as to whether the moon was just peeking above the ridge, or had already risen and was disappearing behind a cloud.
We actually got quite scientific, escalating the passion with each point/counterpoint to make our cases (lest you think this was an unfair contest, I should add that Ashley’s a lawyer). Laurie remained silent. I’m not really sure how long we’d been debating when Laurie finally nudged us and pointed skyward, where, in full view of the entire Western Hemisphere, glowed the landscape illuminating spotlight of the actual full moon. Moon whisperer indeed.
(We never did figure out what the glow was.)

I’ve been in Yosemite for my annual Moonbow and Dogwood photo workshop. Monday night I took the group to Glacier Point for sunset—an unexpected benefit of California’s drought that allowed Glacier Point Road to open weeks earlier than normal. I knew a nearly full moon would be rising above the Sierra crest that evening, but figured that since it would be so far south, we wouldn’t be able to do a lot with it. But when I arrived Glacier Point and saw the moon rising above Mt. Starr King, I realized that shifting slightly south, away from the popular Glacier Point View, might just allow us to include the moon and Half Dome in a wide shot. Hmmm. But because we had people in the group who had never been to Glacier Point, I decided now was not the time for exploration.
As always happens at Glacier Point on these predominantly clear evenings, the light on Half Dome warmed beautifully as the sun dropped to the horizon behind us. Organizing an expansive landscape into a coherent image can be difficult, especially for first timer visitors. But as I moved between the students positioned along the rail, it seemed that all were doing fine and realized that my greatest value at the moment was to stay out of the way. Appreciating the view, I just couldn’t get that moon, blocked by trees from our vantage point, out of my mind.
When a couple of people in the group asked why I wasn’t shooting (it always makes them nervous when the leader is looking at the same view they’re photographing but shows no interest in shooting), I told them I was simply enjoying the view (quite true). But when someone asked if I had any suggestions for something different, my ears perked up. I told them if I were to be shooting, I’d go back up the trail a hundred yards or so to see if I could get around the trees and find something that included the moon.
When several people sounded interested, I warned them that there’s no guarantee we’d find anything photo-worthy, and relocating so close to sunset would risk missing the show entirely. Much to my delight, a couple of people said, “Let’s do it,” and that was all I needed to hear. I told Don (Don Smith, who’s assisting this workshop—for those who haven’t been paying attention, Don assists some of my workshops, I assist some of Don’s, and we do a few workshops as equal collaborations) that I was taking a few people back up the trail and off we went.
I ended up with five (nearly half the group) at the view just below the Glacier Point geology exhibit. I chose this spot for its open view, and for the way it allowed us to frame the scene with Half Dome on the left, triangular Mt. Starr King and the moon on the right, and Nevada and Vernal Falls in the center. With a couple of trees and dark granite for the foreground, the scene couldn’t have been more ideal if I’d have assembled it myself.
I took out my 16-35 and composed this scene that pretty much seemed to frame itself. Even though I had subjects ranging from the fairly close foreground the the extremely distant background, at 21mm I knew I’d have enough depth of field at f11. I used live view to focus on the foreground tree, more than distant enough to ensure sharpness throughout my frame.
While I almost always rely on my RGB histogram to check my exposure, my general exposure technique when photographing a full moon in twilight is to forego the histogram and concentrate on the moon. As far as I’m concerned, a shot is a failure if the moon’s highlights are blown (a white disk), but since the moon is such a tiny part of the frame, it barely (if at all) registers on the histogram. What does register is the blinking highlight alert that signals overexposed highlights. When the foreground is dark, I’ll continue pushing my exposure up until the moon just starts to blink (not the entire disk, just the brightest spots). I know from experience that I can recover these blown highlights in post processing. I also know that this is the most light I can give the scene, because the moon’s brightness won’t change as the foreground darkens. (While I don’t blend images, for anyone so inclined it’s quite simple to take two frames, one exposed for the foreground and the other exposed for the moon, and combine the two in Photoshop.) In this case I spot metered on the foreground to ensure enough light to retain color and detail in the rapidly darkening shadows, then used a Singh-Ray 2-stop hard graduated neutral density filter to hold back the sky and (especially) protect against blowing the moon.

What I love most about photography is its ability to surprise me. Case in point: the final sunset of my recent Yosemite Horsetail Fall workshop, which delivered just one surprise after another.
I’d told my group that we’d get to photograph another moonrise on our last evening, but only if the clouds cooperated. And as the afternoon wore on, it seemed that the clouds that had cooperated so wonderfully all week wouldn’t be on our side tonight. Assembling everyone on the sloped granite above Tunnel View, I eyed the thin (and shrinking) strip of blue sky on the horizon above Half Dome and checked my watch: 5:10—in about fifteen minutes (less than ten minutes before sunset), with no clouds we’d see a full moon poke into view between Half Dome and Sentinel Dome. But our vantage point gave me a clear view of the clouds racing in that direction and our prospects weren’t good. Rather than stress (much), I stayed philosophical: We’d already had three fantastic sunset shoots, expecting a fourth would be downright greedy.
Nevertheless, it was fun to watch the clouds sprint across the sky and pile up behind Half Dome, changing the scene by the minute. Waiting there, I had thoughts about the throngs gathered on the valley floor, hoping (praying) for Horsetail Fall to light up. My group had been lucky on our first two sunsets, but tonight there’d been no sign of sunlight for at least thirty minutes, and with the cloud machine working overtime behind us, I was pretty certain the Horsetail crowd was in for disappointment.
Anticipating a moonrise, I’d gone up our vantage point with just my tripod, 5DIII, and 100-400 lens. Knowing exactly where the moon would appear, my composition was set well in advance—tight, with Half Dome on the far left and the moonrise point on the far right. But without the moon, I realized that the best shots would likely be wide, so I zipped back to the car and returned with another tripod (doesn’t everyone carry two?), my 1DSIII, and my 24-105. Sitting on the (cold) granite, a tripod on my left and my right, I quickly composed a wide shot with my new setup and resumed my vigilance.
By 5:25 I’d stopped watching the incoming clouds, which were streaming in faster than ever, and turned my focus to the moon’s ground-zero, willing the clouds to part for its arrival. At exactly 5:27 and as if by magic, the white glow of moon’s leading edge burned through the trees downslope from Sentinel Dome. I did a double-take—it was as if the moon had pushed the cloud curtain up and slipped beneath. I shouted, “There it is!” and the furious clicking commenced. We ended with about sixty seconds of moonrise, just long enough for the moon to balance atop the trees, before the clouds settled back into place and snuffed it out.
But the surprises had only just begun. While the whole group still buzzed about the moon, I noticed a faint glow on El Capitan. Not quite believing it (and not wanting to jinx anything), I kept my mouth shut and looked closer. But when the glow persisted, I had to point it out, if for no other reason than confirmation that I wasn’t hallucinating. Within seconds all doubts were dispelled as El Capitan exploded with light from top to bottom. So sudden and intense was the light that I’m surprised we didn’t hear the roar from the Horsetail Fall contingent in the valley below us. And rather than fade, as it often does, the light intensified, warming over the next couple of minutes from amber to orange to red. Soon the color deepened to an electric magenta and spread across the sky and all those clouds I’d been silently cursing just a few minutes earlier became allies, catching the color and reflecting it back to the entire visible world.
Giddy about the show, and focused on my two cameras, I’d long given the moon up for dead. So imagine my surprise when, just as the color reached a crescendo, there the moon was, burning through a translucent veil of clouds. So expansive was the scene that a telephoto couldn’t do it justice, so all of my images following the moon’s resurrection were captured with my 5DIII and 24-105. Exposure became trickier by the minute in the advancing darkness, and eventually, pulling detail from the valley without completely blowing out the moon required a 2-stop hard graduated neutral density filter.
Honestly, this was one of those moments in nature that no camera can do justice. I did my best to come find compositions that captured the majesty of Yosemite Valley, the vivid sky and the way it tinted the entire scene, and that Lazarus moon. But take my word for it, you just had to be there….

How many Yosemite moonrise images are too many? I have no idea, but I’ll let you know as soon as I find out.

5:10 p.m.
I stand on the bank of the Merced River, eyes locked on the angled intersection of Half Dome’s sharp northeast edge and its adjacent, tree-lined ridge. If the clouds cooperate, and I’ve done my homework right, a nearly full moon (96%) will be poking above this intersection any minute. We’d been fortunate the first two sunsets of my workshop; dare I hope for one more?
If the moonrise happens as I plan (hoped), the sight could rival what we’d gotten from Horsetail Fall on the first two nights of our workshop. But right now the sky behind Half Dome is smeared with thin-ish clouds—how thin I won’t know until the moon appears (or doesn’t). Gazing heavenward, I find it odd that a moonrise, something that can be predicted with such absolute precision, is so subject to weather’s fickle whim. And the clouds aren’t my only concern—just a half-degree error in my plotting would put the moon behind Half Dome and out of sight.
Few things in nature thrill me more than a moonrise. Camera or not, crescent or full, I love everything about a it: the obsessive plotting and re-plotting that gets me out there in the first place; the hand-wringing anticipation while I await the moon’s appearance; the first white pinprick of moonlight on the horizon (Is that it? There it is!); the ridge-top evergreens silhouetted against the rising disk; the glowing sphere hovering above the darkening landscape; and finally, the moonlit landscape beneath a star-studded sky. Everything.
So it shouldn’t surprise that virtually all of my photo trips—workshops and personal—are scheduled around the moon’s phase and some condition of the night sky. Sometimes I target a full moon, sometimes a crescent, and sometimes I want no moon at all (for dark skies that reveal the most stars)—the choice depends on the kind of moonrise and/or night photography I think best suits the landscape I’m traveling to photograph. But because this workshop is timed to coincide with the few February days that Horsetail Fall might turn a molten red at sunset, a calendar window I shrink even further to avoid the crowds that flock a little later in February, the moon is rarely a priority when I schedule the Horsetail Fall workshop. But I still check. And when I started planning my 2013 Yosemite Horsetail Fall workshop a couple of years ago, I was thrilled to discover that not only could I could time this trip for a full moon, I’d also be able to align that moon with Half Dome at sunset. Twice.
5:13 p.m.
I check my watch: 5:13. Sunset is 5:35; the moon should appear almost adjacent to Half Dome at about 5:15, then slowly rise, like a ball rolling uphill along Half Dome’s left side. By 5:30 the disk will have almost reached Half Dome’s summit, less than its own width with from the granite face. That is, if I’ve done my homework right. 5:14.
Any minute now….
I’d done all my figuring months in advance, which of course didn’t stop me from double-, triple-, quadruple-, and so-on-checking my results in the days leading up to my waiting beside the Merced River with a dozen or so other photographers. Part of my anxiety is the particularly fortuitous alignment of location, moon, and time that put the moon appearance above Half Dome right in my “ideal” sunset window as viewed from one of my favorite Yosemite locations. Not only does this spot provide a clear, relatively close view of Half Dome, it also is at a nice, reflective bend in the Merced River. Even without the moon this is a nice spot, end everyone in the group seems to be finding things to photograph. But I want the moon tonight. Really, really want the moon.
(You really don’t need to read this section)
My moonrise/set workflow was in place long before smartphones apps and computer software laid it all out for any photographer willing to look it up. But those tools are new tricks and I’m an old dog. So here’s how I’ve done it for years:
- Use my topo map software to determine the latitude and longitude of the location I want to photograph.
- Give my location’s latitude and longitude to my Focalware app (or, if I need the data to be a little more granular, the US Naval Observatory website), which returns the moon and sun rise/set altitude (degrees above a flat horizon) and azimuth (the angular distance relative to due north, from 0 to 360 degrees—imagine a clock: 12 is 0 degrees; 3 is 90 degrees; 6 is 180 degrees and so on).
- Next I plug the moon’s altitude/azimuth for my location into the plotting tool of my computer’s mapping software. This draws a line from my location (where I’ll be with my camera) to the location of the moonrise (or set). Most importantly, the line shows the moon’s alignment with whatever landscape feature I’m interested in (such as Half Dome). It also gives me both the distance and the elevation change between my location and the point above which it will rise.
- Finally, I use the elevation and distance data with the trig functions of a scientific calculator to get the altitude to which the moon must rise before it’s visible from my vantage point.
If this all sounds convoluted, that’s probably because it is. I suggest that you try something like The Photographer’s Ephemeris or Photo Pills, which does all this for you. But like I say, that’s a new trick….
5:15 p.m.
I squint, hoping to engage my x-ray vision enough to make out the moon’s outline through the clouds. Nothing. With conditions fairly static, the group has gotten their shots and is chatting more than clicking. Moon or not, the photography will improve as the light warms toward sunset. I walk uphill, away from the river and slightly upstream to improve my angle of view. Still nothing. (Did Ansel Adams experience this angst?)
We’ve reached the time that I expect the moon to appear. I’ve been plotting the moon long enough to be fairly confident within about one moon’s width (a half degree in either direction) of where it will rise, and within plus/minus two minutes of when it will rise. But the whether of seeing a moonrise depends on, well, the weather. Will rain, snow, or even just a rouge cloud shut us out? There’s really no way to know until the day arrives. And sometimes, for example this very instant, I can’t tell whether the sky will cooperate until I actually see the moon.
I’ve learned that the best time to photograph a full moon (when I say “full,” I often mean almost full, generally between 95 and 100 percent of the complete disk illuminated) is during a ten minute window straddling sunset. Much earlier and the light isn’t particularly interesting, and there isn’t enough contrast between the moon and the sky for the moon to stand out dramatically; much later and there’s too much contrast between the moon and everything else in the scene for the camera to handle.
Choosing this location introduces another unknown. Remember when I said that I can pinpoint the moonrise within about its width? Well, in this case that margin of error is just enough to give me pause, because rising slightly to the right of where I think it will rise puts the moon behind Half Dome until about five minutes after sunset. Sentinel Bridge, just a short distance downstream, would have been safer, but the Sentinel Bridge Half Dome shot is far more common, the bridge is usually teaming with people at sunset, and the moon would have been a little higher in the sky during “prime time.” So here we stand.
5:17 p.m.
What’s that faint white blob in the clouds? Without saying anything I squint and look closer. Sure enough, there it is, barely visible, less than one degree above the ridge (its rise above the ridge a couple of minutes ago must have been obscured by the clouds), pretty much where I expect it. Phew. I announce the moon’s arrival to the rest the group, but need to guide their eyes to it. As everyone’s attention returns to their cameras, I cross my fingers for the clear sky in its path to hang in there until at least sunset.
5:25-5:45 p.m.
The moon finally climbs above the clouds and I exhale. Still daylight bright, it now makes a striking contrast against the darkening sky. For the next fifteen minutes we shoot continuously, pausing only to recompose and monitor the highlights. Compositions, which I’d had everyone practice before the moon arrived, range from wide reflections that reduce the moon to a tiny accent, to tight isolations of the moon and Half Dome’s face.
As sunset approaches, the biggest concern becomes those lunar highlights—too small to register on the camera’s histogram, the moon’s face is easily blown out as we try to give the darkening foreground more light. Before we started I made certain everyone has engaged their camera’s Highlight Alert (“blinking highlights”) feature. They all know that when the moon starts flashing, they’ve reached the exposure threshold and must back off on their exposure and lock it in (a few “blinkies” are recoverable in Lightroom or Photoshop, but if the entire disk is flashing, the moon’s detail is probably lost for good)—while the moon will remain the same brightness (can’t take any more exposure), from that point on the foreground will continue darkening until it becomes too dark to photograph. Then we go to dinner.
Like everyone else, I used a variety of compositions. I already have a wide reflection image from a prior shoot, so the image I share here is a moderate telephoto—any tighter (to enlarge the moon further) would have truncated some of Half Dome’s face, something I just cant bring myself to do.
We finally wrapped up at about 5:45, when long exposures to bring out detail in the dark landscape made capturing detail in the bright moon impossible. Everyone was pretty thrilled at dinner, and even though the clouds thickened and washed out our planned moonlight shoot, there were no complaints. And little did we know, Mother Nature had concocted a grand finale for our final sunset.

Winter Moonrise, Merced River, Yosemite
Canon EOS 5D Mark III

ISO 800
F16
Last Friday evening, this professional photographer I know spent several hours photographing an assortment of beautiful Yosemite winter scenes at ISO 800. Apparently, he had increased his ISO earlier in the day while photographing a macro scene with three extension tubes—needing a faster shutter speed to freeze his subject in a light breeze, he’d bumped his ISO to 800. Wise decision. But, rushing to escape to the warmth of his car, rather than reset the camera to his default ISO 100 the instant he finished shooting, he packed up his camera with a personal promise to adjust it later, when his fingers were warmer—surely, he rationalized, removing the extension tubes and macro lens would remind him to reset the ISO too. (You’d think.) But, despite shutter speeds nowhere near what they should have been given the light and f-stop, he just kept shooting beautiful scene after beautiful scene, as happy as if he had a brain.
I happen to know for a fact that this very same photographer has done other stupid things. Let’s see…. There was that time, while chasing a sunset at Mono Lake, that he drove his truck into a creek and had to be towed out. And the two (two!) times he left his $8,000 camera beside the road as he motored off to the next spot. And you should see his collection of out-of-focus finger and thumb close-ups (a side effect of hand-holding his graduated neutral density filters). Of course this photographer’s identity isn’t important—what is important is dispelling the myth that professional photographers aren’t immune to amateur mistakes.
And on a completely unrelated note…
Let’s take a look at this image from, coincidentally, last Friday evening. Also completely coincidentally, it too was photographed at ISO 800 (go figure)—not because I made a mistake (after all, I am a trained professional), but, uhhh, but because I think there are just too many low noise Yosemite images. So anyway….
This was night-two of what was originally my Yosemite ISON workshop—but, after the unfortunate demise of Comet ISON and a week of frigid temperatures in Yosemite, became my Yosemite ice-on workshop. That’s because, to the delight of the workshop students (and the immense relief of their leader), much of the one foot of snow that had fallen the Saturday before the workshop’s Thursday start had been frozen into a state of suspended animation by a week of temperatures in the teens and low-twenties.
Each day we rose to find nearly every shaded surface in Yosemite sheathed in a white veneer of snow and ice. (Valley locations that received any sunlight were largely brown and bare.) And the Merced River, particularly low and slow following two years of drought, was covered in ice in an assortment of textures and shapes from frosted glass to blooming flowers. Adding to all this terrestrial beauty was a waxing moon, nearly full, ascending our otherwise boring blue skies and illuminating our nightscapes.
On Friday night I guided my group to this spot just downstream from Leidig Meadow. There we found the moon, still several days from full, glowing high above the valley floor, and Half Dome reflected by a watery window in the ice. I captured many versions of this scene, from tight isolations of the reflections to wide renderings of the entire display. It’s too soon to say which I like best, but I’m starting with this one because it most clearly conveys what we saw that evening.
I chose a vertical composition because including the moon in a horizontal frame would have shrunk Half Dome and the moon, and introduced elements on the right and left that weren’t as strong as Half Dome, its reflection, and the snowy Merced River. (Sentinel Rock is just out of the frame on the right—as striking as it is, I wanted to make this image all about Half Dome.)
My f16 choice was to ensure sharpness throughout the frame, from the ice flowers blooming in the foreground, to Half Dome and its reflection. As you may or may not know, the focus point for a reflection is the focus point of the reflective subject, not the reflective surface. That means when photographing a reflection surrounded by leaves, ice, rocks, or whatever, you need to ensure adequate DOF or risk having either the reflection or its surrounding elements out of focus. Here I probably could have gotten away with f11, but my iPhone and its DOF app were buried beneath several layers of clothes, and using it would have require removing two pair of gloves.
I’d love to say that I chose ISO 800 to freeze the rapids, but I’m not sure you’d buy it. So I’m sticking with my too many low noise Yosemite images story and moving on. (A few cameras ago, ISO 800 would have meant death to this image, but today, thankfully, it’s mostly just a lesson in humility.)

If there’s anything on Earth more magical than Yosemite with fresh snow, I haven’t seen it. The problem is, Yosemite Valley doesn’t get tons of snow—its relatively low elevation (about 4,000 feet) means the valley often gets rain when most of the Sierra gets snow. And when snow does fall here, it doesn’t stay on the trees for more than a few hours (if you’re lucky). Which is why I’ve always said the secret to photographing snow in Yosemite is to monitor the weather reports and time your visit to arrive before the storm. This strategy gives photographers within relatively easy driving distance, especially those of us without day job, a distinct advantage—from my home in Sacramento I can be in Yosemite Valley in less than four hours (that’s factoring a Starbucks stop in Merced and a fill-up in Mariposa), and I have no problem using darkness to make the roundtrip on the same day.
So last week, when the National Weather Service promised lots of snow in Yosemite for the weekend, I quickly freed up my Saturday. I usually stay just outside the park in El Portal, but because I didn’t want to risk being turned away by a (rare but not unprecedented) weather related park closure, I booked Friday and Saturday nights at Yosemite Lodge, right in the heart of Yosemite Valley—even if the roads shut down, from there I’d be able to walk to enough views to keep me happy all day.
I arrived in the dark to find lots of ice and patches of crusty old snow; I woke dark-and-early Saturday morning to about ten inches of fresh snow. Yippie! The snow fell intermittently throughout the day, with conditions ranging from nearly opaque to classic Yosemite clearing storm drama. Since I was by myself, I was able to deemphasize many of the most frequently photographed spots my workshop expect to photograph and explore random scenes along the Merced. In the morning I concentrated on El Capitan scenes; the afternoon was more about Half Dome.
Of course the classic views are that way for a reason, so, as you can see in this image, I gave them some attention to. Despite not being much of a tourist location, many photographers know about this scene just upstream from Sentinel Bridge. It’s a little hard to find, but usually fairly accessible. But this time getting there forced me to employ a creative parking strategy and to soil about one hundred yards of virgin powder. At this spot a couple of weeks ago I used a telephoto to isolate a single tree clinging to its fall color and reflecting in the river; this visit was my widest lens that got all the work.
The January issue of Outdoor Photographer will include my Yosemite El Capitan Winter Reflection image and a paragraph explaining how to photograph snow in Yosemite Valley. Here’s pretty much what I say there, with a little elaboration:
- Arrive in Yosemite Valley before the storm and plan to stay until it’s over. Getting there before the snow starts makes your life so much simpler; staying until the storm passes not only gets you the coveted “clearing storm” images, it also allows you to photograph all of Yosemite’s iconic features above a snow-covered landscape.
- Despite what Google Maps, your GPS, or your brother-in-law tell you, don’t even think about any route that doesn’t take you through Mariposa and up the Merced River Canyon on Highway 140. The highest point on 140 is Yosemite Valley; all other routes into the park go over 6,000 feet and are much more likely to be icy, closed, or require chains. For people coming from the north that means 99 to Merced and east on 140. Coming from the south, you can either take 99 to Merced (easier) and 140, or 41 to Oakhurst and 49 to Mariposa (faster).
- Carry chains. While you’re rarely asked unless weather threatens, every car entering Yosemite in winter is required to carry them, even 4WD. While 4WD is usually enough to avoid putting chains on, that’s not a sure thing. And if you get caught in a chain check without them, you’re parked right there until the requirement is lifted. If you’re driving your own car to Yosemite, bite the bullet and purchase chains. If you’re flying into California and renting a car, try to get 4WD and keep your fingers crossed that you don’t get asked. Some people will purchase chains and try to return them if they didn’t use them, but that can be risky so check the store’s chain return policy.
- Don’t hole-up in your room while it’s snowing. I generally circle the valley looking for scenes (about a 30 minute roundtrip). If the low ceiling has obscured all the views and you tire of photographing close scenes, park at Tunnel View and wait. Not only is Tunnel View the location of some of Yosemite’s most spectacular clearing storm images, it’s also the first place storms clear. And because you’ll be stunned by how fast conditions in Yosemite can change, waiting at Tunnel View is the best way to avoid missing anything. Another advantage Tunnel View offers is its panoramic view of the entire valley that helps you to decide where to go next. For example, from Tunnel View you can see if Half Dome is emerging from the clouds and there are probably nice images to be had on the east side, or if your best bet will be to stay on the west side and concentrate on El Capitan, Bridalveil Fall, and Cathedral Rocks.
- No matter how spectacular the view is where you are now, force yourself to move on after a while because it’s just as spectacular somewhere else. Trust me.

Wow, it seems like only yesterday that the moon was just tiny dot hovering above Half Dome.

What happened?
No, the moon didn’t magically expand, nor did I enlarge it digitally and plop it into this image. What happened is that I waited two days and moved back; what happened is the difference between 40mm and 400mm; what happened is a perfect illustration of the photographer’s power to influence viewers’ reaction to a scene through understanding and execution of the camera’s unique view of the world.
The rest of the story
My workshop group captured the “small” moon at sunset on Thursday, when it was 93% full and the “official” (assumes a flat, unobstructed horizon) moonrise was 3:09 p.m (an hour and 40 minutes before sunset). That night the moon didn’t rise to 16 degrees above the horizon, the angle to Half Dome’s summit as viewed from our location beside the Merced River, until almost exactly sunset. Because it’s so much higher than anything to the west, Half Dome gets light pretty much right up until sunset—look closely and you can see the day’s last rays kissing Half Dome’s summit.
Flat horizon moonrise on Saturday, when the moon was 100% full, was at 4:24 p.m., only about twenty minutes before sunset. But Tunnel View is nearly 500 feet above Yosemite Valley; it’s also 5 1/2 miles farther than Half Dome than Thursday’s location—this increased elevation and distance reduces the angle to the top of Half Dome to just 6 degrees. So, despite rising over an hour later, when viewed from Tunnel View, the moon peeked above the ridge behind Half Dome just a couple of minutes after sunset (if we’d stayed at Thursday night’s location, in addition to being hungry and cold, by Saturday we’ have had to wait until after 6:00 for the moon to appear).
Exposure
My objective for full moon photography is always to get the detail in the moon and the foreground. As I mentioned in yesterday’s post, these were workshop shoots, and experience has shown me that the most frequent failure when photographing a rising moon in fading twilight is getting the exposure right—the tendency is to perfectly expose the foreground, which overexposes the daylight-bright moon (leaving a pure white disk). This problem is magnified when the moon catches everyone unprepared.
So, both evenings I had my group on location about 30 minutes before the moon. While we waited I made sure everyone had their blinking highlights (highlight alert) turned on, and understood that their top priority would be capturing detail in the moon. I warned them that an exposure without a blinking (overexposed) moon would slightly underexpose the foreground. And I told them that once they had the moon properly exposed (as bright as possible without significant blinking highlights), they shouldn’t adjust their exposure because the moon’s brightness wouldn’t change and they’d already made it as bright as they could. This meant that as we shot, the foreground would get continually darker until it just became too dark to photograph.
(A graduated neutral density filter would have extended the time we could have photographed the scene, but the vertical component of Yosemite’s horizon made a GND pretty useless. A composite of two frames, one exposed for the moon and one exposed for the landscape would have been a better way to overcome the scene’s increasing dynamic range.)
Compare and contrast
Winter Moonrise, Half Dome, Yosemite
Thursday night’s scene, which would have been beautiful by itself, was simply accented by the (nearly) full moon. Contrast that with my visit a few years ago, when I photographed a full moon rising slightly to the left of its position last Saturday’s night. But more significant than the moon’s position that evening was the rest of the scene, which was so spectacular that it called for a somewhat wider composition that included the pink sky and fresh snow. And then there’s the above image, from last Saturday night—because the sky was cloudless (boring), and snow was nowhere to be seen, I opted for a maximum telephoto composition that was all about the moon and Half Dome.
The wide angle perspective I chose Thursday night emphasized the foreground by exaggerating the distance separating me, Half Dome, and the moon; the snowy moonrise image found a middle ground that went as tight as possible while still conveying the rest of the scene’s beauty. Saturday night’s telephoto perspective compressed that distance, bringing the moon front and center. Same moon, same primary subject: If Thursday night’s moon was a garnish, Saturday’s was the main course.

The highlight of my just completed Yosemite Autumn Moon photo workshop was a full moon rising above Half Dome at sunset. But rather than settle for just one Half Dome sunset moonrise, I’d “arranged for” three. Clouds shut us out on sunset-moonrise number two, but sunset-moonrise number one was a huge success. (And sunset-moonrise number three, from Tunnel View, was so special that I’ll dedicate a whole blog post to it.)
Any location’s “official” sun and moon rise/set times assume a flat horizon—if you read that today’s moonrise is at 5:00 p.m., you need to account for the time it takes for the moon to rise above whatever obstacles (mountains, hills, trees) are between you and the flat horizon. And due to the same motion around Earth that causes the moon’s phases, anyone planted in the same location night after night would see the moon rise about fifty minutes later each day (this is an average—the nightly lag varies with many factors). For example, a moon that hovered right on the horizon at sunset last night will rise too late to photograph tonight.
While you can’t do anything about the moon’s absolute position in the sky, you can control the elevation of your horizon simply by changing your location. In other words, careful positioning makes it possible to photograph a moonrise at sunset on multiple nights—move lower and/or closer to the horizon to delay the moon’s appearance, higher and/or farther to view the moon sooner.
The earlier the moon will rise, the closer to your subject (for example, Half Dome) you should be to increase the angle of view; the later the moonrise, the farther back and higher you should be. So, positioning ourselves on the valley floor, close to Half Dome, provided a steep angle of view that delayed the moon’s appearance on Thursday night, when it rose (above a flat horizon) several hours before sunset. Conversely, standing at elevated Tunnel View a couple of nights later decreased our angle of view, enabling us to see the moon sooner when official moonrise is closer to sunset.
Last Saturday night, from Tunnel View on Yosemite Valley’s west side (farthest from Half Dome) the moon was “scheduled” to appear about five minutes after sunset—that would put it in the magenta, post-sunset band with just enough light for about ten minutes of shooting before the dynamic range (the brightness difference between the sunlit moon and darkening foreground) shut us down. While that was the shoot we were most looking forward to, for Friday night I’d picked a mid-valley spot by the Merced River that would put the moon above Half Dome just about sunset. And for our initial sunset on Thursday evening, I took the group to a riverside spot on Yosemite Valley’s east side, much closer to Half Dome.
Clouds obscured the moon Friday night, but Thursday night was a real treat. Not only did we find the fall color in the cottonwood trees upriver still hanging in there (despite a fairly early autumn in most of Yosemite Valley), the clouds parted just in time for the moon’s arrival. In addition to Half Dome, the trees, and the moon in the distance, we were able to get a mirror image of the scene reflected on the glassy surface of the Merced River at our feet.
While the downside of moving closer to Half Dome (or whatever your subject is) is that the wider focal length necessary to include the entire scene also shrinks the moon, I’ve always believed a small moon adds a powerful accent that makes an already beautiful scene even more special. But what if you prefer your moon big? Simple: just wait a day or two, and move back as far as possible. Stay tuned….

One final point: Notice the cool (blue) color cast of this scene. This is an indication of not just the rapidly advancing twilight, but also the depth of the shade there in the shadow of the steep valley walls and dense evergreens. An image’s color temperature is a creative choice made during processing by photographers capturing in raw (unprocessed) mode. While warming the light would have made the trees more yellow, I decided that the coolness adds a soothing calmness that is lost in the warmth of a daylight scene.

Usually an image comes together on the spot, an organic blend of location and light unique to the moment. But some images I carry around in my brain for years, fully aware of the elements and how I want them assembled, and hopeful to be present when that happens. I have a number of these “dream” images rattling around between my ears, and every once in a while the stars align and I actually get to capture one. For example, on every visit to Sentinel Dome I would eye the granite indentations on the southeast flank and picture them as pools of rainwater reflecting the sunset sky, framing Half Dome in the distance. Wouldn’t it be great if….
One showery October afternoon a few years ago I made the hike to Sentinel Dome with these indentations in mind. I knew that the recent rain would quite likely have filled them, allowing at least part of my dream to come true. After summiting the dome I beelined to the other side and found “my” pools exactly as I’d hoped. The sky was a promising mix of blue and gray, but the sun was still at least an hour above the horizon. Nevertheless, the air was clean and western horizon was clear, essential ingredients for the colorful sunset I so wanted. Dare I hope?
I walked around a bit and mentally refined my composition—rather than set up close and use an ultra wide-angle, I moved back as far as the terrain would permit. This allowed me to fit the pools in the frame at a longer a focal length, which would compress the distance separating Half Dome and the pools. To reduce the expanse of granite behind the pools, I flattened my tripod as far as it would go and framed my shot. With closest pool about six feet in front of me, stopping down to f20 and focusing on a point about twelve feet away gave me sharpness throughout the frame. With my composition set and waiting on my tripod, I readied my two-stop hard graduated neutral density filter and adjusted my polarizer, then sat down on the (hard) granite, and waited.
The sunset color that finally came was more than I dared hope for. The sun was at my back, but with clouds overhead and the western horizon wide open, the crimson glow stretched all the way to the eastern horizon. I clicked this frame when the color was at its most intense, so brilliant in fact that every exposed surface seemed to throb with its glow.

Often, including a rising or setting moon will turn an ordinary landscape into something special. Of course, like most things worth doing, moon photography adds a couple of layers of complication: First, there’s the matter of getting there at the right time, with the moon in the right place (it does little good to arrive as the moon rises if it’s skewed 90 degrees from the scene you came to photograph); and once you have everything lined up, you still have to contend with the almost always tricky exposure issues.
A little lunar geometry (you can skip this section of you’re more interested in “how” than “why”)
Many factors, some within our control, some completely beyond our control, determine the time, location, and phase of the moon at any time. The factors beyond our control are things like the earth’s rotation and the moon’s orbit, which determine the moon’s phase and its absolute position in the sky. On the other hand, we can control our location, and take the steps necessary to get us in the right place at the right time.
A full moon always rises and sets directly opposite the sun, rising in the east at sunset and setting in the west at sunrise. This actually makes perfect sense when you take a little time to understand the monthly choreography of the earth, moon, and sun. Just as the earth revolves around the sun, the moon revolves around the earth; at any point in this dance, half of the earth is lit (daytime) and half of the earth is dark (nighttime), half of the moon is lit and half of the moon is dark.
What we on earth see as a full moon is simply that one day each month that the moon’s entire lit side faces the earth’s dark side—that is, when the earth is directly between the sun and the moon (picture a beam of light that follows a straight line that starts at the sun, passes through earth, and ends on the moon). On that day only, as the point of your location on earth rotates from day to night, you’ll see the sun disappear in the west and the moon rise in the east. As the earth keeps rotating away from daylight and into night, the full moon rises higher and higher, reaching its highest point around midnight, then dropping as your location rotates back toward the sunlit side (and sunrise).
So then why do we rarely see a full moon rising exactly as the sun sets? That’s because: 1) the point of maximum fullness (when the sun, earth, and moon align perfectly) only happens at one instant each month—at every other instant of each month’s full moon day, the moon is only almost full (but still full enough to appear completely full); and 2) sun/moon rise/set times we see published always assume a flat horizon—if you have mountains between you and the horizon, your view of the actual sun/moon rise/set will be blocked.
Due to its monthly orbit about the earth, each day (or night) the moon rises a little later and gains or loses a little bit of its disk (the farther it has revolved from that sun->earth->moon line, the less of the moon’s lit side we see). So the night after the moon is full, it rises after sunset and is a little less full. The next night it rises a little later still, and is even less full, and so on. Eventually (in a little more than two weeks after it was full) the moon has revolved all the way around the earth until it lies between the earth and sun (now our imaginary line goes sun->moon->earth); all of its sunlit side faces away from the earth and we have a new (invisible) moon.
We call the moon “new” because the night before it disappears into the sun, all that was left of the shrinking moon (that was completely full about two weeks ago) was a small sliver that shined briefly on the eastern horizon just before sunrise, then disappeared as soon as the sky brightened (it’s still up there, but completely overpowered by the sun’s brightness). The next day the moon won’t appear at all because seeing it would require looking directly into the sun; but the following day, there it is, this time as a thin sliver on the western horizon immediately after sunset (again, it was up there most of the day, we just can’t see it until the sun sets and the sky darkens). This brand new crescent slips below the horizon shortly after it appears. And for the next two-plus weeks it will rise a little later, and grow a little larger, each night, until it’s full again and rising at sunset. Cycle complete.
If we do the math (this won’t be on the test), we can infer that if the moon takes 29.5 days to complete its cycle (from full to new and back to full), and there are 24 hours in a day, the moon must be rising about 50 minutes later each day (29.5/24=48.8). This rough approximation varies with many factors; for simplicity I usually round it to an hour when I do rough calculations in my head. And I always rely on much more precise software or astronomical charts for my critical calculations.
Locating the moon
Those who don’t do a lot of moon photography are amazed at how much the moon shifts above the landscape throughout the year—you can sight a full moon rising between Half Dome and El Capitan one month, and a few months later it’ll be rising above Leaning Tower (far to the south). Fortunately, like many things in nature that appear random to the uninformed, there is actually nothing random about the moon’s location once you take the time to figure it out.
If the idea of figuring anything saps the pleasure from your photography (or sends you into a panic), you’ll be happy to know that sometimes it’s enough to simply know that the moon will be rising in the east a little before sunset (this info is available in many places, in many forms, but the most complete source I’ve found is the US Naval Observatory website). Armed with that knowledge, you can go out to a location with a view of the western horizon, wait for the moon to appear, and start shooting.
On the other hand, juxtaposing the moon with a specific landmark requires more planning. And because its position is so not random, many others have done the heavy lifting for the rest of us. There are far too many moon phase/position resources to name even a small percentage of them, so rather than even try, I’ll just give you a couple of techniques, and the tools that enable them:
- My old fashioned way (old trick for an old dog): I figured out my technique for locating the moon long before computer software and smartphone apps took away most of the effort. Nevertheless, I continue to do it this way because I’ve already done all the hard work (figuring out how to do it), and I can do it in the field, with zero connectivity (no wifi or cell signal required). After relying for years on a the US Naval Observatory website for the info I need (moon phase and moon/sun rise, set, altitude, and azimuth), I now get all the pertinent data from my Focalware iPhone app (I never said I’m opposed to new technology), plugging it into my National Geographic Topo! (that’s NG’s exclamation point, not mine) mapping software (discontinued) to plot the direction of the moon’s rise/set. To determine when the moon will appear above (or disappear behind) the surrounding terrain, I plug distance and elevation information from Topo! into the trigonometric functions of my HP 11C scientific calculator (originally an actual calculator, but now also an iPhone 11C emulation app) to compute the elevation in of my horizon.
- Software (the better way for 99.999 percent of you): The Photographer’s Ephemeris (a free computer download or fairly inexpensive smartphone app) is the most complete solution that I know of (though I’m sure there are others I don’t know of)—I probably would have never taken the time to figure out my technique if TPE had been available. Not only does TPE give you the sun and moon’s location and elevation above the flat horizon, it also figures out the the actual (terrain included) horizon. The downside is that because it uses Google Maps, TPE requires connectivity and is better used in advance of your shoot (usually not a problem). Recent TPE versions also allow you to download the maps to your device for offline access—if I were a TPE user, I’d be doing this before every trip.
Exposure
My rule for photographing a rising/setting full moon is that I must capture detail in the landscape and the moon. If my landscape is black (or just too dark), or my moon is a white disk (or blob), my image has failed. But since the post-sunset landscape is in full shade, and the moon is as bright as a sunlit landscape (because it is a sunlit landscape), the dynamic range of a full moon scene is pretty extreme, often too extreme for a camera to handle with a single click (always my goal).
But here’s the great part—if you figure that the moon rises about an hour later each day, and the full moon rises at sunset, then it stands to reason that the day before it’s full the moon will rise about an hour before the sun sets. Factoring in the terrain on the horizon (and assuming you’re not at the base of a mountain), that means that the day before the moon is full is the best opportunity to photograph a nearly full (say 97%, give or take a percent or two) moon rising in the east above a landscape painted with the warm sunlight of the golden hour. Conversely, if your view is to the west, you can photograph a nearly full moon setting in warm sunrise light the day after it’s full. Either way, the day before or after the full moon gives you everything you need to capture your scene in nice, photographable light that’s still sufficient to hold the moon’s highlights at bay.
I’ve found that if I’m really careful with my exposure, I can usually capture enough foreground and lunar detail until five or ten minutes after sunset. Shooting after sunset usually requires raw capture, then massaging the dark foreground brighter, and bright moon darker, in the raw processor. A graduated neutral density filter can increase this threshold to maybe fifteen or twenty minutes after sunset—after that my foreground is unusably dark (or my moon is recoverably bright).
Another technique that works when the light gets too extreme is a composite—two images, one exposed for the landscape and the other exposed for the moon, combined in Photoshop. In the “Rules According to Gary,” this isn’t cheating if you don’t change the size or position of the moon. (Though it doesn’t break my rules, I no longer do composites because I have this weird compulsion to get everything with one click.)
The final piece of exposure advice I’ll add is to make sure your camera’s blinking highlights (also called highlight alert) are set (as far as I’m concerned, they should be set anyway because I see no downside to highlight alert). The moon is usually so small in your frame that it won’t register in the histogram, which means blinking highlights are usually the only way to know that you’re blowing out the moon. I monitor my highlights closely after each exposure and have found that, when shooting raw (jpeg shooters don’t have as much margin for error), I can usually recover enough detail with an exposure 2/3 to 1 stop brighter than the exposure that first showed blinking.
Just do it
Like most things photographic, don’t expect resounding success the first time you try adding a full moon to your landscape. But each time you go out, not only will you improve, you’ll probably come away with ideas for how to do it differently the next time.
