Two Trees Against Boulder, Ten Lakes Basin

September 17, 2009 G Dan Mitchell Leave a comment

Two small trees growing against the face of a large boulder in the Ten Lakes Basin, Yosemite National Park, California.

Earlier in the day I had wandered down from “lake three” to “lake two” in Ten Lakes Basin (where there are apparently actually seven lakes – go figure!). My goal was partly just to see one more of the lakes, but I also wanted to scope out some photographic possibilities during the day so that when I returned later in the evening I would be able to get to work more quickly. This pair of trees was on my “maybe” list, so when I returned in the evening I photographed the subjects on the “definite” list first and then turned my attention to a group of trees growing closely around a large glacial (I assume) boulder.

Whatever the aesthetic result, this was not an easy photo to do on a technical basis. Since it was late and the lake was in deep shade behind a large mountain ridge to the west there was not a lot of light to work with, and what light there was trended a bit strongly toward blue. On top of that the wind was blowing like crazy, making camera stability a bit of an issue – not to mention the problem of shooting waving tree branches with the long exposures the conditions required. In the end I resorted to a regular strategy that included making quite a few exposures, trying to time them for brief pauses in the wind, and being willing to accept a small amount of motion blur.

Edge of the Shadow, Ten Lakes Basin

September 16, 2009 G Dan Mitchell Leave a comment

The shadow from tall cliffs to the west of Ten Lakes Basin moves across a small meadow near the base of the cliffs, Yosemite National Park, California.

Although I have backpacked in the Sierra and in Yosemite for many decades and have visited many parts of the back-country so often that I know individual rocks and trees (!), I’m almost embarrassed to admit that I had not been into the Ten Lakes Basin until my trip in late August. I’ve looked up at the valley through which the trail to the Basin climbs as I’ve driven past on Tioga Pass Road but I’ve always thought of this location as not high enough for me since I prefer the highest sub-alpine terrain.

This little clearing in the forest is located between what some call “lake three and lake four,” the two lakes up the creek from the largest lake in the center of the Basin, which is the one where most people seem to camp. (I camped at “lake three” and had it entirely to myself for two nights.) Because the ridge to the west of the Basin is so high and steep and close to these lakes, the shadow from the ridge begins to block the light quite early in the day.

Granite Benches above Blue Lake

September 14, 2009 G Dan Mitchell Leave a comment

Evening sunlight strikes the trees scattered along the granite benches above Blue Lake, John Muir Wilderness, Sierra Nevada, California.

Although the scene here looks quite peaceful and quiet, the truth is that it was freezing cold and a very strong wind was blowing. A very unusual early August weather system moved across the Sierra on this night and there was even a threat (unrealized) of some snow flurries. The broken clouds passing quickly overhead created fast-moving shadows that tracked across the terrain, producing the pattern of shadow and light on this steep area of granite benches and trees above Blue Lake.

Lupine, Upper Sabrina Basin

August 19, 2009 G Dan Mitchell 7 Comments

We had hiked up through this meadow filled with plants and wildflowers earlier in the day while walking a circuit that included Hungry Packer Lake (beyond the saddle seen in the distance and below Picture Peak), Moonlight Lake, and Sailor Lake. At that time the early afternoon light had been far too harsh for photography, so I made plans to be back here early in the evening. I had hoped for some “golden hour” light, but I have to admit that I could see that a ridge to the right was going to cast a shadow here too early for that. Fortunately, the light on the peak came from the side such that it wasn’t as much brighter as it might otherwise have been, and it seemed like it might be possible to capture the huge dynamic range of this scene.

That last point brings up a difficult technical issue with this photograph – that tremendously large dynamic range. Although my eyes/brain could take in the full scene while standing there, no camera that I’d be carrying on the trail can possibly deal with this in a single shot. In the foreground the meadow plants were in early evening/late afternoon shade while the cloud above the peak was brightly lit by the direct sun. In the film days the only real option would have been to use a graduated neutral density (GND) filter to reduce the light from the sky. However, with digital capture we have another alternative – capturing several exposures of the scene optimized for the bright and dark areas and then combining them in post-production. That is precisely what I determined to do here.

In this case I made a main exposure that handled the middle of the dynamic range of the scene. I also made two more; one optimized to barely contain the brightest levels in the cloud and the second optimized to capture all of the details in the darker foreground meadow. The three versions of the scene were combined in post-processing to recreate something much closer to what I actually saw. (Yes, this was a complex photograph to realize!) in addition to using three exposures, I was also able to carefully customize the boundaries between them issuing masks – both of which would be impossible with a GND filter.
