Morning light on a tree-covered peninsula along the edge of a subalpine lake with a talus slope backdrop, Yosemite National Park.

I think that the primary thing that first caught my attention in this little scene was the very twisted and curving tree about 1/3 of the way in from the right edge of the frame. I wonder why one tree ended up growing in such an odd way when its neighbors seem to have managed to grown in a straight and conventional manner? The light on these trees was coming from almost directly behind them, as the sun had just topped the ridge above and out of the frame. Because the talus slope is fairly steep, portions of it remain in shade.

This photograph posed a few interesting challenges, and they are probably not all immediately apparent. One that may be visible to those who are familiar with such scenes is the fact that back-light like this can create some very bright highlights that can “blow out” in a digital camera exposure. In fact, these highlights are what determine the exposure for such a scene. If accommodating the bright highlights makes the shadows too dark, I can either work a bit in post to bring back some shadow detail or I can make a separate exposure for the shadows and blend the two in post. That wasn’t necessary here – I was able to capture the scene in a single exposure. The second odd little problem was that swarms of mosquitos were flying just above the water all around the shoreline of the lake. Although you cannot see them in this small jpg, there were many, many little traces of the bugs in the air – so many, in fact, that I had to somewhat laboriously clone out a good number of the most obvious of them.

Morning light on the trees, boulders, and grasses of a sub-alpine Sierra Nevada lake, Yosemite National Park.

On the morning after my hike up to this lake we were all up early and eager to explore the surrounding area. Everyone rose well before sunrise, and we headed off in various directions for our first morning of exploration and to start shooting. I began in the forest, looking for some corn lily plants and then various snags and fallen trees, but I eventually ended up along the shoreline of the lake. A lake like this one has almost limitless subjects to photograph. I began working the edge of the lake by photographing a few shoreline trees, then moved on to photograph some large boulders in the lake not far from the shore. As I moved clockwise along the edge of the water I began to pick up one of my favorite subjects – trees back-lit by morning light – and I worked to find a few compositions that spanned the bright foreground rocks and grasses, the middle distance shoreline trees, and then the more distant and shaded talus slopes leading to overhead ridges.

There were six of us in the group, and it was interesting to observe the different ways we each worked. Everyone was up pretty early, but for the most part each photographer headed off to look for his own special subjects. Occasionally we would run into one another, but we most often took pains to not try to re-do one another’s shots. Some among us immediately began to explore a bit more widely, heading around the lake and into the forest along the far shore, while others started very close to our campsite and slowly began to expand their circle of subjects. Over the course of a number of days we all got to know the lake and its surroundings much better – there is nothing like staying in one place for three or four days to reveal it in more depth than might be apparent on a short overnight visit.

Granite Ridge and Trees, Afternoon Light

Afternoon light back-lights a glaciated granite ridge partially covered with trees, Yosemite National Park.

Late in the afternoon – almost more like early evening, actually, the atmosphere at this spot along the Tuolumne River valley in the Yosemite back-country was “complex” – both challenging to shoot and full of interesting and varied potential. You might be able to see in the upper right portion of the image that a good part of the sky was obscured by a thin gray layer of high clouds, and by looking at the very faint a low contrast view of the more distant mountains at the upper left it is clear that the atmosphere was quite hazy, especially when back-lit. Yet, there is sunlight slanting across the expanse of granite and trees on the foreground ridge, and this light picks off some of these trees.

This was the kind of lighting that requires some patience. And fortunately I had gotten myself to a beautiful spot on top of a granite “whaleback” (a low and long dome-like structure) above a small side valley beyond which this ridge was arranged with the more distant ridge in the background. Most of the time the light was what I’ve heard one of my friends simply describe as “blah.” The atmosphere was a bit hazy, most of the light was obscured by the high clouds (and the haze), and even in this quite beautiful spot most of the time nothing much stood out as a photograph.

Such scenes require – and can teach – patience. It helps to find yourself alone on a granite ridge without much else to occupy your time and with no other particular task at hand. It also helps if you have learned that there is nothing at all wrong with sitting quietly in one spot for a couple of hours and simply observing. And, if you have done these things before and have observed these scenes, you know that there is a possibility that even in light and landscape that might seem a bit “blah,” there is the potential for a momentary bit of light to create something worth photographing. This was a perfect afternoon for that sort of shooting.

Tuolumne River Below Glen Aulin, Morning. Yosemite National Park, California. September 16,2011. © Copyright 2011 G Dan Mitchell – all rights reserved.

Early light on morning clouds above the Tuolumne River Canyon below Glen Aulin, Yosemite National Park.

This is the same bend in the Tuolumne River, located below Glen Aulin and before the river descends toward Waterwheel Falls and eventually the abomination of Hetch Hetchy Reservoir, that was shown in a photograph of late afternoon light that I posted here a few days ago. This time it was early morning. We had been up well before sunrise and had wandered off in various directions to find early morning photographic subjects. My main goals were the cascading water along the edge of this section of the river (a bit of which is visible in the lower portion of the frame) and a granite bowl to the right of this view. As I came over the rise above this area before descending I saw the beautiful sparse clods to the west, probably extending to the edge of the Sierra and still with pastel colors from dawn light.

A technical observation about this photograph. This scene presented a technical challenge in the form of an extremely wide dynamic range between the bright and red-saturated first direct sunlight on the ridge at upper left and the much darker areas of forest in shade along the river and in the foreground. With a digital exposure, in a scene like this one, the primary rule for me is “don’t blow out the highlights.” If I had overexposed the sky the clouds would have turned into pure white, texture-free blotches and that bit of early sun on the rocks would have lost detail and taken on a very strange coloration. However, an exposure that protects the highlights in a scene like this one can leave the shadows nearly black. While it is possible to “fix” that a bit in post, the result is not necessarily very good when the dynamic range is very large. One “traditional” solution would have been to use a graduated neutral density filter (or “GND”) that blocked some of the brightest areas at the top of the frame while not affecting the lower 2/3 or so. But I don’t use them, and in this case the result would not have been totally wonderful since the same filtering that would reduce sky brightness would also make the large granite dome at the right end up nearly black at the top.

So instead of filtering at the time of exposure, I decided that I would use the roughly comparable, but more flexible, “exposure blending” techniques in post. With that in mind I made several photographs at different exposures – some at shorter shutter speeds to avoid the blown out highlights and others at increasingly slower shutter speeds to reveal the shadow detail that my eyes could see but which the camera otherwise could not. During the post-production phase, I selected two of the exposures, one that was as bright as possible but without blowing out the sky and sunlight, and the other two stops lighter to reveal that shadow detail in a way that seemed consistent with what I recall the scene actually looked like. The two source images were carefully adjusted during raw conversion and their two layers carefully aligned. With the darker image (the one with the “good” sky) on the top, I began to “paint” out the mask to reveal the details of the foreground forest, river, and rocks. (In answer to the expected question, this is not the same as HDR. That is a more or less automated process that works in a different way. Exposure blending is typically a manual process that relies a great deal on the photographers judgment and recall of the actual scene.)
