Among the many things I’m giving thanks for this Thanksgiving weekend is the return of rain and snow to California. Normally I’d have rearranged my schedule to be in Yosemite for the season’s first snow, but because family trumps photography, I had more important things to do. So Yosemite will just have to be beautiful without me.
As much as I love photographing Yosemite with fresh snow, spending quality time family this weekend was a no-brainer for me. I can’t say that foregoing a photo opportunity has always been so easy (and I’ve been blessed with a family that would have understood had I abandoned them for a day or two to chase the snow), but never let it be said that I’ve learned nothing from my photography career.
In general, being self-employed has time challenges that I’m still learning to manage, but I’m getting better. I do have to admit that sometimes the idea of a 9-5 job with weekends and paid vacations sounds mighty good (I realize I’m speaking in very general terms and don’t mean to offend anyone pinned a cubicle 12 hours per day just to pay the bills), but the bottom line is that I love the flexibility of having complete control of my schedule.
When I left the 9-5 world 15 years ago to pursue this crazy passion, the missing safety net was a great motivator—I was only as successful as the next art show (which I no longer do) or photo workshop. Weekends? Holidays? Irrelevant. And the closest thing I got to a vacation was when my wife and I would travel to a new location to scout for a new workshop.
But as the years go by (is it me, or is time moving faster?), I’ve come to appreciate the autonomy of self employment. I can look at my calendar, whether the day be tomorrow or two years from now, and if nothing’s there, I can do whatever I want. Of course that might mean cramming the things that need to be done into times when others might be watching Netflix from their recliner or body-surfing at the beach, but it’s 100 percent my choice and I love it.
I often tell people that photography must be a source of pleasure, but there’s a difference between happiness and pleasure, and I know now that what I really mean is that photography must make you happy. I probably would have gotten great pleasure from my images had I gone to Yosemite this Thanksgiving weekend, but I know in the long run I’m much happier for my choice to stay home.
A few words about this image
I’d love to give you a detailed description of the entire process that went into photographing this beautiful scene, but I have no specific memory of its capture. I took it at the beginning of a March visit to Yosemite, one of those semi-spontaneous up and back trips I do when the Yosemite forecast calls for snow. I can infer from my exposure settings (specifically, because I was at ISO 50 and f/16) that I was going for a little motion blur to smooth the ripples in the Merced River. But since my shutter speed was .6 seconds, I must have decided that adding a neutral density filter would have robbed the river of some of its texture. (Or maybe I was just too lazy to fish my ND from my bag.) I can also tell by looking at the clouds and the snow on the trees that the snow had just stopped, but not necessarily for good (this is confirmed by the images preceding this one on the card).
The real lesson in this image is the reminder that we all have a lot of unmined gems on our hard drives. I found this one a few weeks ago by employing an approach I often use when I have extra time between trips: picking a previously processed image taken in particularly nice conditions, and revisiting other images from that shoot.
When you make your living from photography, often (usually) the business part of it has to take priority over the photography part, and there just aren’t enough hours in the day for everything. In a perfect world I’d identify and process every single keeper the day after returning from a trip, but that’s simply not possible because of that whole time thing. So possible keepers slip through the cracks and languish on my hard drive(s). But that’s okay, because I never delete anything, and I get comfort from the knowledge that whenever I need a new image, I don’t need to run out with my camera and make one right now.
Not only is this retro photography exercise productive, it’s far more fun than it should be—kind of like finding money on the sidewalk (with none of the guilt about benefiting from someone else’s misfortune).

A few days ago I posted an El Capitan in winter image on Instagram. Since it had been nearly three years since that trip, a lot of the specifics of that day had slipped my mind, but when I pulled up the Instagram image’s raw file in Lightroom to check the capture info, a few more of that day’s (so far unprocessed) images caught my eye. The next thing I knew, I was processing this one, and gradually, some of the day’s details returned to me.
Yosemite Valley had been brown and dry beneath an overcast sky when I checked into the lodge the evening prior, but I woke the next morning to a world of white. (This was no surprise—I’d made the trip because snow was forecast.) The snow was still falling after breakfast, and as usually happens in a Yosemite storm, the clouds completely obscured all of Yosemite’s icons. But knowing that the key to photographing snow in Yosemite is to be out in it when the storm breaks, I was quite content to drive into its midst and wait it out. And break it did, turning to flurries with a mix of clouds and blue sky by late morning. The conditions stayed like that the rest of the day and I was in photographer heaven.
I circled Yosemite Valley all day, sometimes targeting specific spots, other times just pulling over when something moved me. By the time the sun set I was pretty certain that I had lots of good stuff on my card, but most important, I was happy. (If just spending time with your subject, regardless of the photographic results, doesn’t make you happy, you probably should be photographing something else.)
On my way out of the park after sunset I made one last stop to photograph this Valley View scene. With its easy access and riverside views of El Capitan, Cathedral Rocks, and Bridalveil Fall, Valley View is low-hanging photography fruit. And it’s especially nice with fresh snow. I’d already stopped here at least once before on that day, capturing last week’s Instagram image late that morning, but I couldn’t resit taking one more peek before heading down the canyon and home.
After the trip I processed a couple of images right away, but like so many of my photo trips, most of the images from this day have languished on a hard drive, victims of the priorities of running a business. This whole experience has been a good reminder of how many unprocessed images I have “in the bank,” waiting to be processed. It has inspired me to make a concentrated effort to go back through my archives to see what might be lurking there. I’ve already excavated a couple besides this one, with more on the way.
And speaking of low hanging fruit, I’ve started by going through my Yosemite snow images, because, well…, how can you go wrong with Yosemite and snow?
Because winter is right around the corner, and we’ve already entered (just barely) the window when snow is possible in Yosemite, here’s my recipe for photographing Yosemite with snow.
The Early Bird Gets the Snow
If you delay your trip until you hear that it snowed in Yosemite, you’re too late. That’s because Yosemite is only 4,000 feet above sea level and actually warmer in winter than most of the United States. When it does snow there, as soon the snow stops, Yosemite’s relatively mild temperatures collude with sunshine, wind, and gravity to clear the trees in a matter of hours. Not only that, park visitors, driven to shelter by the storm, swarm outside to gape as soon as the snow stops, quickly marring the pristine beauty with footprints, not to mention the mud spread by their boots and tires. In other words, the key to photographing Yosemite with snow is being in the park during the storm (and working fast).
Monitor the weather
All winter I monitor the Yosemite weather forecast for hints of a cold storm. But even this isn’t as simple as you might expect—the single biggest mistake people make when planning a Yosemite snow trip is opening whatever weather site or app is convenient and simply typing in Yosemite. Yosemite Valley is only 4,000 feet above sea level, and virtually the entire rest of the park is higher—up to 13,000 feet elevation. And for some reason, even though Yosemite Valley is where you want to be for snow (and pretty much the only place in Yosemite you can be in winter), most weather resources don’t give the forecast for Yosemite Valley. Instead, they pick some other (random?) elevation that is almost always more likely to get snow than Yosemite Valley. You’d be amazed at how much more frequently snow falls just 500 feet above Yosemite Valley than falls in Yosemite Valley, which means a lot of people end up driving to Yosemite to photograph the snow their weather app promised, then end up marinating all day in a cold rain.
I know there are lots of weather forecast options out there, but most lack the resources of the National Weather Service (or they just use the NWS data). The NWS may not always nail the forecast, but they seem to be more consistent and reliable than any of the other options. But even selecting a generic NWS Yosemite forecast can lead you astray. I recently typed “Yosemite” into the NWS’s forecast input field and was given an assortment of similar options, each of which returned a different location in Yosemite (most not Yosemite Valley). So rather than leave it to chance, to ensure a forecast for the correct elevation, I’ve bookmarked the NWS point forecast for Yosemite Valley.
When it snows in Yosemite, they do sometimes require chains. Usually 4WD or AWD cars with snow tires are exempt, but not necessarily. Regardless of the conditions, park rules say if you plan to drive in the Yosemite in winter, you must carry chains—even if you have 4WD/AWD. My Subaru Outback is AWD, but when the weather is threatening, I have been asked if I have chains. So they’ve never asked me to prove it, or had to put chains on, but I always carry chains because if they do find that you don’t have chains when they’re required, you’ll need to just park until it chain requirement is lifted.
Driving to Yosemite
Sometimes the chain requirements aren’t for Yosemite Valley, but they do apply to two of the three routes into Yosemite Valley. When a storm is possible, the best way to avoid snow, ice, and chain requirements is to ignore the guidance of your GPS and Google Maps and enter via Mariposa on Highway 140, which comes up the Merced River Canyon and doesn’t ever get as high as 4,000 feet until Yosemite Valley. (Trust me on this.)
That said, any route into Yosemite is subject to closure or restrictions due to slides, flooding, or downed trees. Always check the Yosemite and Caltrans road conditions pages before you leave (I sometimes check them on the way too).
Weather in Yosemite is very changeable, and a storm forecast that looked promising one day can completely fizzle the next—or vice versa. Some trips I’ve had a week to prepare for, others I didn’t consider going until I woke up and checked the Yosemite forecast that morning. Because I want to be ready at the drop of a hat, all winter long in the back of my Outback are my chains and a duffle bag with all my cold weather gear: waterproof pants, parka, and shoes, wool hat and gloves, and an umbrella.
When possible, I like to be in Yosemite the day before the snow starts. That said, it isn’t usually difficult to get a room in Yosemite at the last minute when a winter storm threatens, and there have been times when I’ve actually waited until I arrived in the park before booking my room (not necessarily a strategy I’d recommend). Nevertheless, the later I wait to leave, the more likely I’ll be delayed or turned back by a road closure.
Once the snow arrives, rather than hole up in my room, I’m out shooting. Even though Yosemite’s storms often erase all signs of its most recognizable features, stormy weather is a great time to photograph swirling clouds and accumulating snow in glorious (and rare!) solitude. Nice soft light too.
As much as I love photographing Yosemite when snows, the poor visibility and near white-out snowfall can reach a point of diminishing photographic returns. But even then, I don’t go in (or home). Instead, I park at Tunnel View and wait for the weather to clear. Tunnel View is the perfect place to wait out a Yosemite storm because it’s on the west side of Yosemite Valley (where the clearing usually starts), provides an elevated vantage point with a view all the way up the valley to Half Dome, and is spectacular to photograph when the storm clears. It even has decent cell service. And if I’m looking for an excuse to turn on the engine and warm things up, I drive through the tunnel for the view westward, a preview of coming weather.
My final advice for anyone is, when the storm clears, move fast and don’t spend too much time at any one spot, no matter how beautiful it is. It’s a pretty safe bet that if the conditions are beautiful right here, you’re probably missing opportunities elsewhere. The peak conditions, with snow draping every exposed surface, don’t last long, so get your shots and move on—or risk missing out. (This is the voice of experience talking.)

What’s the point?
It seems like one of photography’s great mysteries is achieving proper focus: the camera settings, where to place the focus point, even the definition of sharpness are all sources of confusion and angst. If you’re a tourist just grabbing snapshots, everything in your frame is likely at infinity and you can just put your camera in full auto mode and click away. But if you’re a photographic artist trying to capture something unique with your mirrorless or DSLR camera and doing your best to have important visual elements objects at different distances throughout your frame, you need to stop letting your camera decide your focus point and exposure settings.
Of course the first creative focus decision is whether you even want the entire frame sharp. While some of my favorite images use selective focus to emphasize one element and blur the rest of the scene, most (but not all) of what I’ll say here is about using hyperfocal techniques to maximize depth of field (DOF). I cover creative selective focus in much greater detail in another Photo Tip article: Creative Selective Focus.
Beware the “expert”
I’m afraid that there’s some bad, albeit well-intended, advice out there that yields just enough success to deceive people into thinking they’ve got focus nailed, a misperception that often doesn’t manifest until an important shot is lost. I’m referring to the myth that you should focus 1/3 of the way into the scene, or 1/3 of the way into the frame (two very different things, each with its own set of problems).
For beginners, or photographers whose entire scene is at infinity, the 1/3 technique may be a useful rule of thumb. But taking the 1/3 approach to focus requires that you understand DOF and the art of focusing well enough to adjust your focus point when appropriate, and once you achieve that level of understanding, you may as well do it the right way from the start. That ability becomes especially important in those scenes where missing the focus point by just a few feet or inches can make or break and image.
Back to the basics
Understanding a few basic focus truths will help you make focus decisions:
Depth of field discussions are complicated by the fact that “sharp” is a moving target that varies with display size and viewing distance. But it’s safe to say that all things equal, the larger your ultimate output and closer the intended viewing distance, the more detail your original capture should contain.
To capture detail a lens focuses light on the sensor’s photosites. Remember using a magnifying glass to focus sunlight and ignite a leaf when you were a kid? The smaller (more concentrated) the point of sunlight, the sooner the smoke appeared. In a camera, the finer (smaller) a lens focuses light on each photosite, the more detail the image will contain at that location. So when we focus we’re trying to make the light striking each photosite as concentrated as possible.
In photography we call that small circle of light your lens makes for each photosite its “circle of confusion.” The larger the CoC, the less concentrated the light and the more blurred the image will appear. Of course if the CoC is too small to be seen as soft, either because the print is too small or the viewer is too far away, it really doesn’t matter. In other words, areas of an image with a large CoC (relatively soft) can still appear sharp if small enough or viewed from far enough away. That’s why sharpness can never be an absolute term, and we talk instead about acceptable sharpness that’s based on print size and viewing distance. It’s actually possible for the same image to be sharp for one use, but too soft for another.
So how much detail do you need? The threshold for acceptable sharpness is pretty low for an image that just ends up on an 8×10 calendar on the kitchen wall, but if you want that image large on the wall above the sofa, achieving acceptable sharpness requires much more detail. And as your print size increases (and/or viewing distance decreases), the CoC that delivers acceptable sharpness shrinks correspondingly.
Many factors determine the a camera’s ability to record detail. Sensor resolution of course—the more resolution your sensor has, the more important it becomes that to have a lens that can take advantage of that extra resolution. And the more detail you want to capture with that high resolution sensor and tack-sharp lens, the more important your depth of field and focus point decisions become.
The foundation of a sound approach to maximizing sharpness for a given viewing distance and image size is hyperfocal focusing, an approach that uses viewing distance, f-stop, focal length, and focus point to ensure acceptable sharpness.
The hyperfocal point is the focus point that provides the maximum depth of field for a given combination of sensor size, f/stop, and focal length. Another way to say it is that the hyperfocal point is the closest you can focus and still be acceptably sharp to infinity. When focused at the hyperfocal point, your scene will be acceptably sharp from halfway between your lens and focus point all the way to infinity. For example, if the hyperfocal point for your sensor (full frame, APS-C, 4/3, or whatever), focal length, and f-stop combinition is twelve feet away, focusing there will give you acceptable sharpness from six feet (half of twelve) to infinity—focusing closer will soften the distant scene; focusing farther will keep you sharp to infinity but extend the area of foreground softness.
Because the hyperfocal variable (sensor size, focal length, f-stop) combinations are too numerous to memorize, we usually refer to an external aid. That used to be awkward printed tables with long columns and rows displayed in microscopic print, the more precise the data, the smaller the print. Fortunately, those have been replaced by smartphone apps with more precise information in a much more accessible and readable form. We plug in all the variables and out pops the hyperfocal point distance and other useful information
It usually goes something like this:
You’re not as sharp as you think
Since people’s eyes start to glaze over when CoC comes up, they tend to use the default returned by the smartphone app. But just because the app tells you you’ve nailed focus, don’t assume that your work is done. An often overlooked aspect of hyperfocal focusing is that app makes assumptions that aren’t necessarily right, and in fact are probably wrong.
The CoC your app uses to determine acceptable sharpness is a function of sensor size, display size, and viewing distance. But most app’s hyperfocal tables assume that you’re creating an 8×10 print that will be viewed from a foot away—maybe valid 40 years ago, but not in this day of mega-prints. The result is a CoC three times larger than the eye’s ability to resolve.
That doesn’t invalidate hyperfocal focusing, but if you use published hyperfocal data from an app or table, your images’ DOF might not be as ideal as you think it is for your use. If you can’t specify a smaller CoC in your app, I suggest that you stop-down a stop or so more than the app/table indicates. On the other hand, stopping down to increase sharpness is an effort of diminishing returns, because diffraction increases as the aperture shrinks and eventually will soften the entire image—I try not to go more than a stop smaller than my data suggests.
Keeping it simple
As helpful as a hyperfocal app can be, whipping out a smartphone for instant in-the-field access to data is not really conducive to the creative process. I’m a big advocate of keeping photography as simple as possible, so while I’m a hyperfocal focus advocate in spirit, I don’t usually use hyperfocal data in the field. Instead I apply hyperfocal principles in the field whenever I think the margin of error gives me sufficient wiggle room.
Though I don’t often use the specific hyperfocal data in the field, I find it helps a lot to refer to hyperfocal tables when I’m sitting around with nothing to do. So if I find myself standing in line at the DMV, or sitting in a theater waiting for a movie (I’m a great date), I open my iPhone hyperfocal app and plug in random values just to get a sense of the DOF for a given f-stop and focal length combination. I may not remember the exact numbers later, but enough of the information sinks in that I accumulate a general sense of the hyperfocal DOF/camera-setting relationships.
Finally, something to do
Unless I think I have very little DOF margin for error in my composition, I rarely open my hyperfocal app in the field. Instead, once my composition is worked out and have determined the closest object I want sharp—the closest object with visual interest (shape, color, texture), regardless of whether it’s a primary subject.
Of course these distances are very subjective and will vary with your focal length and composition (not to mention the strength of your pitching arm), but you get the idea. If you find yourself in a small margin for error focus situation without a hyperfocal app (or you just don’t want to take the time to use one), the single most important thing to remember is to focus behind your closest subject. Because you always have sharpness in front of your focus point, focusing on the closest subject gives you unnecessary sharpness at the expense of distant sharpness. By focusing a little behind your closest subject, you’re increasing the depth of your distant sharpness while (if you’re careful) keeping your foreground subject within the zone of sharpness in front of the focus point.
And finally, foreground softness, no matter how slight, is almost always a greater distraction than slight background softness. So, if it’s impossible to get all of your frame sharp, it’s usually best to ensure that the foreground is sharp.
Why not just automatically set my aperture to f/22 and be done with it? I thought you’d never ask. Without delving too far into the physics of light and optics, let’s just say that there’s a not so little light-bending problem called “diffraction” that robs your images of sharpness as your aperture shrinks—the smaller the aperture, the greater the diffraction. Then why not choose f/2.8 when everything’s at infinity? Because lenses tend to lose sharpness at their aperture extremes, and are generally sharper in their mid-range f-stops. So while diffraction and lens softness don’t sway me from choosing the f-stop that gives the DOF I want, I try to never choose an aperture bigger or smaller than I need.
Now that we’ve let the composition determine our f-stop, it’s (finally) time to actually choose the focus point. Believe it or not, with this foundation of understanding we just established, focus becomes pretty simple. Whenever possible, I try to have elements throughout my frame, often starting near my feet and extending far into the distance. When that’s the case I stop down focus on an object slightly behind my closest subject (the more distant my closest subject, the farther behind it I can focus).
When I’m not sure, or if I don’t think I can get the entire scene sharp, I err on the side of closer focus to ensure that the foreground is sharp. Sometimes before shooting I check my DOF with the DOF preview button, allowing time for my eye to adjust to the limited light. And when maximum DOF is essential and I know my margin for error is small, I don’t hesitate to refer to the DOF app on my iPhone.
A great thing about digital capture is the instant validation of the LCD—when I’m not sure, or when getting it perfect is absolutely essential, after capture I pop my image up on the LCD, magnify it to maximum, check the point or points that must be sharp, and adjust if necessary. Using this immediate feedback to make instant corrections really speeds the learning process.
Sometimes less is more
The depth of field you choose is your creative choice, and no law says you must maximize it. Use your camera’s limited depth of field to minimize or eliminate distractions, create a blur of background color, or simply to guide your viewer’s eye. Focusing on a near subject while letting the background go soft clearly communicates the primary subject while retaining enough background detail to establish context. And an extremely narrow depth of field can turn distant flowers or sky into a colorful canvas for your subject.
There’s no substitute for experience
No two photographers do everything exactly alike. Determining the DOF a composition requires, the f-stop and focal length that achieves the desired DOF, and where to place the point of maximum focus, are all part of the creative process that should never be left up to the camera. The sooner you grasp the underlying principles of DOF and focus, the sooner you’ll feel comfortable taking control and conveying your own unique vision.
About this image
Yosemite may not be New England, but it can still put on a pretty good fall color display. A few years ago I arrived at Valley View on the west side of Yosemite Valley just about the time the fall color was peaking. I found the Merced River filled with reflections of El Capitan and Cathedral Rocks, framed by an accumulation of recently fallen leaves still rich with vivid fall color.
To emphasize the colorful foreground, I dropped my tripod low and framed up a vertical composition. I knew my hyperfocal distance at 24mm and f/11 would be 5 or 6 feet, but with the scene ranging from the closest leaves at about 3 feet away out to El Capitan at infinity, I also knew I’d need to be careful with my focus choices. For a little more margin for error I stopped down to f/16, then focused on the nearest rocks which were a little less than 6 feet away. As I usually do when I don’t have a lot of focus wiggle room, I magnified the resulting image on my LCD and moved the view from the foreground to the background to verify front-to-back sharpness.

As we enter the fall color photography season, I’m revisiting and revising previous articles. This is the second in the series.
Vivid color and crisp reflections make autumn my favorite season for creative photography. While most landscape scenes require showing up at the right time and hoping for the sun and clouds to cooperate, photographing fall color is often a simple matter of circling the scene until the light’s right. For the photographers who understand this, and know how to control exposure, depth, and motion with their cameras, great fall color images are possible any time of day, in any light.
Backlight, backlight, backlight
The difference between the front-lit and backlit sides of fall foliage is the difference between dull and vivid color. When illuminated by direct sunlight, the side of a leaf opposite the sun throbs with color, as if it has its own source of illumination, while the same leaf’s lit side appears flat—if you ever find yourself thinking that the fall color seems washed out, check the other side of the tree.
While the backlight glow isn’t as pronounced in shade/overcast, when the leaves are illuminated by light that’s spread evenly across the sky, even diffuse sunlight is far more pronounced one side of the leaves than the other, giving the side of a leaf that’s opposite the sky (the side getting less light) a subtle but distinct glow when compared to its skyward side.
Isolate elements with a telephoto for a more intimate fall color image
Big fall color scenes are great, but a telephoto or macro enables you to highlight and emphasize elements and relationships. Train your eye to find leaves, groups of leaves, or branches that stand out from the rest of the scene. Zoom close, using the edges of the frame to eliminate distractions and frame subjects. And don’t concentrate so much on your primary subject that you miss complementary background or foreground elements to balance the frame and provide an appealing canvas for your subject.
Selective depth of field is a great way to emphasize/deemphasize elements in a scene
Limiting depth of field with a large aperture on a telephoto lens can soften a potentially distracting background into a complementary canvas of color and shape. Parallel tree trunks, other colorful leaves, and reflective water make particularly effective soft background subjects. For an extremely soft background, reduce your depth of field further by adding an extension tube to focus closer.
Underexpose sunlit leaves to maximize color
Contrary to what many believe, fall foliage in bright sunlight is still photographable if you isolate backlit leaves against a darker background and slightly underexpose them. The key here is making sure the foliage is the brightest thing in the frame, and to avoid including any sky in the frame. Photographing sunlit leaves, especially with a large aperture to limit DOF, has the added advantage of an extremely fast shutter speed that will freeze wind-blown foliage.
Slightly underexposing brightly lit leaves not only emphasizes their color, it turns everything that’s in shade to a dark background. And if your depth of field is narrow enough, points of light sneaking between the leaves and branches to reach your camera will blur to glowing jewels.
A sunstar is a great way to liven up an image in extreme light
If you’re going to be shooting backlit leaves, you’ll often find yourself fighting the sun. Rather than trying to overcome it, turn the sun into an ally by hiding it behind a tree. A small aperture (f16 or smaller is my general rule) with a small sliver of the sun’s disk visible creates a brilliant sunstar that becomes the focal-point of your scene. Unlike photographing a sunstar on the horizon, hiding the sun behind a terrestrial object like a tree or rock enables you to move with the sun.
When you get a composition you like, try several frames, varying the amount of sun visible in each. The smaller the sliver of sun, the more delicate the sunstar; the more sun you include, the more bold the sunstar. You’ll also find that different lenses render sunstars differently, so experiment to see which lenses and apertures work best for you.
Polarize away the foliage’s natural sheen
Fall foliage has a reflective sheen that dulls its natural color. A properly oriented polarizer can erase that sheen and bring the underlying natural color into prominence. To minimize the scene’s reflection, slowly turn the polarizer until the scene is darkest (the more you try this, the easier it will be to see). If you have a hard time seeing the difference, concentrate your gaze on a single leaf, rock, or wet surface.
A polarizer isn’t an all-on or all-off proposition. Slowly dial the polarizer’s ring and watch the reflection change until you achieve the effect you desire. This is particularly effective when you want your reflection to share the frame with submerged feature such as rocks, leaves, and grass.
Blur water with a long exposure
When photographing in overcast or shade, it’s virtually impossible to freeze the motion of rapid water at any kind of reasonable ISO. Rather than fight it, use this opportunity to add silky water to your fall color scenes. There’s no magic shutter speed for blurring water—in addition to the shutter speed, the amount of blur will depend on the speed of the water, your distance from the water, your focal length, and your angle of view relative to the water’s motion. When you find a composition you like, don’t stop with one click. Experiment with different shutter speeds by varying the ISO (or aperture as long as you don’t compromise the desired depth of field).
Reflections make fantastic complements to any fall color scene
By autumn, rivers and streams that rushed over rocks in spring and summer, meander at a leisurely, reflective pace. Adding a reflection to your autumn scene can double the color, and also add a sense of tranquility. The recipe for a reflection is still water, sunlit reflection subjects, and shaded reflective surface.
When photographing leaves floating atop a reflection, it’s important to know that the focus point for the reflection is the focus point of the reflective subject, not the reflective surface. This is seems counterintuitive, but try it yourself—focus on the leaves with a wide aperture and watch the reflection go soft. Achieving sharpness in your floating leaves and the reflection requires an extremely small aperture and careful focus point selection. Often the necessary depth of field exceeds the lens’s ability to capture it—in this case, I almost always bias my focus toward the leaves and let the reflection go soft.
Nothing communicates impending winter like fall color with snow
Don’t think the first snow means your fall photography is finished for the year. Hardy autumn leaves often cling to branches, and even retain their color on the ground through the first few storms of winter. An early snowfall is an opportunity to catch fall leaves etched in white, an opportunity not to be missed. And even after the snow has been falling for a while, it’s possible to find a colorful rogue leaf to accent an otherwise stark winter scene.

Lots of variables go into creating a successful landscape image. Many people struggle with the scene variables—light, depth, and motion—that are managed by your camera’s exposure settings: shutter speed, f-stop, ISO. Others struggle more with the composition variables: identifying, isolating, and framing a subject. (I’m not denying that there’s overlap between the exposure and composition sides of image creation, but leveraging that overlap requires independent mastery of both sides.)
Getting the exposure variables out of the way
Because I want to write more about the composition decisions that went into this image, I’ll only touch briefly on my exposure choices for the above image. I approach every scene with at my camera’s best ISO (100) and lens’s “ideal” f-stop (generally f11, where lenses tend to be sharpest, the depth of field is good, and diffraction is minimal).
Given that motion wasn’t a factor (I was on a tripod, the wind was calm, and the river’s motion didn’t concern me), I stuck with ISO 100. And even though the submerged rocks provided lots of visual interest in the immediate foreground, my 16mm focal length provided more than enough depth of field at f11—focusing about four feet into the scene would give me sharpness from around two feet to infinity. That was easy.
With those two variables established, I spot-metered on the brightest part of the scene and set dialed my shutter speed until the exposure was as bright as felt I could get away with without hopelessly blowing the highlights. This ensured that my scene (shadows included) was as bright as I could safely make it.
Here’s what I was thinking
Reflections of El Capitan, Cathedral Rocks, and Bridalveil Fall make Valley View one of the most photographed locations in Yosemite Valley. I usually I try to find something a little different than the standard view here, but the cloudy vestiges of a passing storm reflecting in the Merced River provide an irresistible opportunity to take advantage of everything that makes Valley View so special.
Some scenes you can walk up to and plant your tripod pretty much anywhere without much difference in your background subjects (though that’s rarely the case with foreground/background relationships). That’s not the case at Valley View, where the difficulty starts with distracting, non-photogenic shrubs on the near riverbank—to keep them out of the frame, you need to hop the rocks all the way down to the river.
The bigger problem at Valley View is getting all the primary elements into the image—too far to the left, and El Capitan disappears behind a stand of evergreens; too far to the right and another stand of evergreens occludes most or all of Bridalveil Fall. I moved into the fifteen-foot section of riverbank that gives me what I consider an adequate view of both, and started studying the submerged and protruding rocks right in front of me, looking for a workable foreground.
I’ll often move around quite a bit to control foreground/background subject relationships; in this case I found little benefit from shifting and stayed more or less in the same place. But that doesn’t mean I didn’t vary my shots—I tried a variety of compositions, but wide and tight, horizontal (above) and vertical (below). Some used lots of sky, while others (like this one) minimized the sky to emphasize the foreground. Still others were of the reflection only, or of the reflections with just a thin stripe of the opposite riverbank. The other variable I played with was my polarizer, which I turned to maximize and minimize the reflection, plus a combination (like both images here).
As with many images, composition at the top of the page required some compromises. I liked the way the vertical version leads the eye through the scene, and frames it with the two most striking elements—El Capitan and Bridalveil Fall. But I also wanted a horizontal rendering that would open up the scene and express its broad grandeur.
An often forgotten component of successful photography is what gets left out—an image’s perimeter are frequently home to distractions overlooked by photographers too drawn to their primary subjects. So the problem making a Valley View horizontal composition that’s wide enough to include the reflection and river rocks, is the introduction of potentially distracting elements on the far left and right.
In this case my greatest problem was the scene’s left side, with its bare trees, brown riverbank, and exposed rocks, it was rife with potential distractions to deal with. Shifting the entire composition to the right would have thrown the frame off balance, and added a lot of real estate that wasn’t worthy of the scene. Going tighter would have sacrificed too much river rock and reflection, an essential feature in my mind. I could have removed my shoes and socks, rolled up my pants, and walked forward through the (frigid) water—that move would have solved all my problems, but probably wouldn’t have been appreciated by all the other nearby photographers.
I ended up using the trees and rocks to frame the left side of the image, taking care to allow the entire arc of the riverbank to complete so it didn’t look like the nearby rocks (on the left) belonged a different scene. The vertical version doesn’t have these problems, and though it sacrifices the breadth of the horizontal composition, hold a gun to my head and I might tell you it’s the vertical version I prefer. (But it’s nice to have a choice.)
