Granite slabs littered with exfoliated boulders, Yosemite Naitonal Park.

As is our pattern in the backcountry, by late afternoon each of photographers in our group had “headed out” find subjects to photograph in late-day light. There was a lot to work with in the area surrounding the lake where we were camped; low ridges, the shoreline of the lake, forest, meadow with boulders, granite slabs, and even actual mountains if you walked far enough.

I decided to wander to the other side of our lake, where a granite dome rise above the water… and dropped of precipitously into a gigantic canyon on the other side. I decided that I would approach from one side, cross the summit close to sunset, and then return to camp by descending a ridge on the other side. The angle of the light was quite low as I crossed granite slabs to a low spot between the dome and another low hill, and the slabs were covered with boulders that appeared to be remnants of the process of exfoliation.

This had been a challenging day for photography for the most part. While there was some good light in the early part of the day, later on the sky was covered by monsoonal clouds and building thunderstorms. It never really rained much where I was, but the potential was there and it did rain not far away. Thunderstorm photography can be exciting, especially if you are in a position where you can see the tops of the clouds… but down below, if the sky is completely overcast, the light can become blah and gray.

But there is always a hope that evening will bring a break-up of the clouds and even allow in some sunset light. By the time I made this photograph that process was already starting. The uniform cloud ceiling had begun to break up, with openings to blue sky here and there, and an occasional beam of light moved over the landscape. Here the light from the west, shining in beneath the clouds, illuminated the foreground meadow and the gigantic forests winding up the slopes toward granite peaks further away.

I’m often out before the first light and then again as the last sunlight turns to dusk. These are not the only times of day worth photographing, but they are times that often produce beautiful light and colors and effects, with warm light and dramatic shadows. Many times — even during the busiest times of the year — I have stood it some of the most impressive locations and witnesses the most astonishing light… almost alone. I don’t know whether to encourage everyone to get up early and stay out late or to perhaps just keep relatively quiet and enjoy the solitude! I sometimes wonder how different our ideas of the Sierra are, depending upon when we are out and about as more or more than where we go.

In a spot like this one, the arrival of morning light is a highly dynamic thing — not at all a static or even slow-moving event. For example, here the light is raking across the foreground granite slab the tilts down from left to right, at the angle of the light is only briefly ideal to light the trees without also lighting the granite. The whole transition from first light on tree tops to a bit too much on the granite might take little more than a minute.

Sierra Nevada Trees And Granite

I originally worked up this photograph for an article on the relationship between supposed realism in photographs and post-processing. (“Photographs And Reality: A Complicated Relationship”) I selected it because the scene posted a particular common challenge, namely a dynamic range that was wider than the typical dynamic range of presentation media, and because capturing the full scene required me to make some exposure decisions that intentionally produce an original “straight out of camera” image that wasn’t lovely, but which protected the scene data I would need to work with the photograph in post.

The subject is a group of large-trunk trees growing on granite slabs at the base of a Yosemite high country granite dome. This landscape — more or less the landscape of much of Yosemite — is interesting in so many ways. Here the trees seem to somehow grow out of little more than cracks in solid granite, and shortly beyond where they stand the rock becomes too steep and too solid to support more large trees. While such scenes can be found throughout the park and in many more inaccessible areas, this one is right alongside Tioga Pass Road!
