Aspen trees with golden autumn leaves grow among boulders on a rocky eastern Sierra Nevada slope

Before my single day of eastern Sierra Nevada aspen photography this season, I had been concerned about the quality and timing of the color – and reports by some other photographers who visited just before I was there were not encouraging. Reports mentioned trees that had turned earlier than usual (true) and trees that turned without producing special color and so forth. Compounding my concerns just a bit was the fact that my schedule required me to be there a bit earlier than the time I would typically regard as being prime for aspen color. But I’d rather shoot one day of less-than-stupendous aspen color than miss the entire show, so up into the eastern Sierra above Bishop, California we drove.

I was pleased to find that there was actually a lot of great color. Some of the usual “hot spots” that people seem to flock to were perhaps not as amazing as they can be, but after photographing the aspens for some years I have found some odd little personal places where I could find good color – and in a few places color that was downright excellent. I photographed these trees rather late in the day, perhaps after many people who prefer to photograph aspens in the sun had already left. I intentionally sought out an area that I knew would be in shade since I often prefer the muted and softer light this brings. Here the trees are not quite so thick since they grow on very difficult and rocky slopes. But what they lacked in density they made up for in color!

Post-Processing: A Shadow Recovery Example

4 Comments

Note that this is an older article from 2012. While the concepts are largely the same with contemporary cameras and software, some aspects of the article are now a bit date.

(In another forum someone asked a question – actually, more like posed a challenge – related to how much usable detail and quality could be extracted from a raw file that contained areas of very low luminosity, as could happen with a badly underexposed image or with an image of a scene with a very large dynamic range. Since I went to the work of responding and illustrating my response, I figured that I might as well share it here, too. With minor revisions, here it is.)

First, I actually have a “real” version of this photograph in which highlights were slightly blown, but which I preferred to use since I could bring them back in post and get a bit more shadow detail to start with. (It looks a bit bright to me as an on-screen jpg, but it makes a fine print.) That photograph ended up looking like this:

Morning light slants over the top of sandstone cliffs above early autumn foliage in Kolob Canyon, Zion National Park

This photograph and the other I’ll move to below were both shot from a tripod with a Canon EOS 5D Mark II at ISO 100 using the Canon EF 24-105mm f/4L IS at f/16. While the “keeper” used for the photograph above had a 1/4 second exposure, the example I’ll use below was shot at 1/30 second.

The exposure challenge in this scene was the very large dynamic range between the bright spot of sky at the head of the canyon and the much darker colorful foliage in relatively deep shadow in the foreground. Exposing for optimal quality in the foreground would completely blow out the sky, while exposing for the sky would necessarily grossly underexpose the foreground.

I originally thought that I might like to have four bracketed exposures in case that would let me produce a better final image via layer blending, but it turned out to be unnecessary and the final image (as shown above) has a single source file with no blending. However, this means that I still happen to have one very badly underexposed (by three stops) version at 1/30 second which I’ll use here as the starting point for what I plan to illustrate in this post. Follow along with me and see what I can do with the very underexposed version of the file…

Frost-Rimmed Oak Leaves, Autumn

A very cold autumn morning brings a touch of frost to late-fall oak leaves in Yosemite Valley

Earlier this week I had (just barely) enough time for a very quick one-day up-and-back visit to Yosemite Valley. Such a visit, entailing a four-hour drive each way, and beginning with a 3:30 a.m. alarm going off, is not completely fun in all imaginable ways… but I won’t complain in front of people who might regard a visit to this valley as a once-in-a-lifetime experience. I’m fortunate to live where I’m able to get to such a place and back in a day. The reason for the quick visit was that I had not made my annual “autumn leaves” visit to the Valley. In a typical year I do that right around the first of November (though I often think of it as a Halloween trip!) when the maple, oak, and dogwood leaves can be very colorful. I thought that I had missed the show this year, but over the weekend I heard from friends that there were still leaves in The Valley, so I figured that I would try to get up there for a quick visit.

Having gone there for decades, I no longer go straight for the usual iconic subjects – though I will photograph them when the conditions are extraordinary. Instead, I often end up poking around in odd corners, looking for things that are smaller and less easily seen, but which I associate with The Valley just as much as, say, Half Dome or El Capitan or Yosemite Falls. So, odd as it may seem, when I made my first stop of the day at El Capitan Meadow, with its iconic views of Sentinel Rocks and El Capitan on opposite sides of The Valley… I spent the first 15 minutes with my lens pointed down into a small patch of the Merced River where there were some interesting reflections, and then I wandered off along the river bank in a few inches of snow to photograph close-up views of the wonderful oak leaves rimmed with morning frost. It occurred to me later that some might think it is a bit odd to drive so far to photograph such things!

Aspen Grove, North Bishop Creek

An aspen grove along North Bishop Creek in late afternoon light.

While I like huge, expansive groves of aspens, I also like small, isolated groups, especially when set against the background of what I think of as sage brush country. This group of trees is actually part of a long, thin grove that stretches along a small dirt side road up in the Bishop Creek drainage. The grove and the road are on my “must visit” list for my annual aspen-chasing trips to the eastern Sierra, so by now I’ve learned a lot about the “personality” of this particular spot. Like a number of other spots to which I return each year, you might not notice anything spectacular about this grove – but by means of repeated visits I have learned where to look for certain little subjects: a creek that flows past boulders beneath colorful trees, a particular thick grove of very thin-truck trees, groves of trees that seem barely taller than I am.

I made this photograph in what might seem like unlikely lighting conditions. It was late afternoon, and the trees were back-lit. The sun was close to dropping behind the very tall ridge that lies above and beyond the border of the photograph, so the light was angling across the several background ridges running down into the valley, and lighting their upper edges. And, of course, the leaves glow when the light come through them from behind.
