Rocky Shoreline, Lower Young Lake

July 12, 2011 G Dan Mitchell 5 Comments

Morning light shines through the forest on the rocky shoreline of Lower Young Lake, Yosemite National Park.

The three Young Lakes are among my favorite places in the Yosemite back-country, and I visit them pretty much every summer. As I did when I made this photograph, I most often to in the last season – I like to visit after Labor Day weekend, when the crowds begin to diminish, the weather is a bit cooler, fall colors begin, and everything in the Sierra seems to slow down in anticipation of the coming winter.

On this visit I camped for something like three nights at the lower lake, and thus had time to photograph throughout the basin at different times of day. On this morning I got up early as I usually do, and spent a good part of the morning photographing along the shoreline of this lake, starting in the area near where most people camp and where the trail passes along the shoreline. A bit later I crossed the outlet stream and followed the rocky shoreline around to the far shore where the forest opens into rocky meadows near the main inlet stream.

In the photograph, the early light is coming from behind the trees in the shoreline forest and glancing off the tops of the boulders on the shore and in the shallow water. There were two photographic challenges in making this photograph. First, the dynamic range between the brightest sunlit spots on the rocks and the darker areas in the forest is extreme. In some cases I might resort to blending multiple exposures as a way to deal with this issue, but here I was able to recover enough detail from a single frame. The second issue relates to the color of the light. Specifically, while the sunlit areas have a fairly warm quality, the light in the shadows on the rocks and in the shaded areas of the forest turns out to be distinctly blue in a photograph. In fact, these areas end up looking much more blue than you would think if you were there – this has to do with the way our minds process what we see to make it more like what we think it should be… if that makes any sense. In any case, the decisions here ended up being about how much blue would be the right amount.

Mist, Trees, and Boulders – Cascade Creek

July 5, 2011 G Dan Mitchell Leave a comment

Mist and spray from spring runoff fill the air in the boulder-strewn canyon of Cascade Creek, Yosemite National Park.

Making this photograph was an “interesting” experience! I visited Cascade Creek on June 18, probably near the peak flow of the spring runoff season, and the creek was a full-blown torrent. After photographing some familiar rock formations below the bridge that crosses the creek, I decided to try a photograph from the upstream side of the bridge. In this direction, the creek is more or less half waterfall and half cascade as it plunges down a very steep and narrow section of the hillside. The whole scene was in deep shade and mist and spray filled the air.

I made a guess that a 135mm lens might give me a tight enough framing of the scene, so I briefly stepped away from the creek and the spray-filled air to switch lenses. Leaving everything else behind, I took the camera, tripod, and this single prime lens and walked to the wet side of the bridge. There was enough spray that I and my gear began to get wet pretty fast, so I worked quickly. I got everything in what I figured would be about the right position before I uncovered the lens, then quickly uncovered and finalized the composition and manually focused. I knew that I couldn’t really stay in this spray all that long so I spent a couple minutes bracketing a series of exposures as the mist surrounded me, hoping that water on the lens and in the air in front of the camera would not interfere with the shot.

The main decision was about shutter speed and with other decisions regarding aperture and so forth to follow on that. The idea was to use a slow enough shutter speed to allow the water to blur a bit, but not so slow as to turn it to formless mist. I managed to get to a 1/5 second exposure by shooting at f/20, an aperture a bit smaller than I would typically want to use, as apertures smaller than about f/16 can begin to introduce a bit too much diffraction blur. But in a shot like this one where mist is obscuring a great deal of the detail anyway, that seemed like a reasonable compromise that let me lengthen the shutter speed just a bit.

Mammoth Peak and Kuna Crest, Overflowing Tuolumne River

July 1, 2011 G Dan Mitchell Leave a comment

Mammoth Peak and the Kuna Crest loom above as the Tuolumne River overflows its banks and floods surrounding meadows on a frosty spring morning, Yosemite National Park.

As I drove from Lee Vining Canyon over Tioga Pass and toward the Tenaya Lake area early in the morning, I came to the Tuolumne River where it passes under the bridge beneath the highway in the Tuolumne Meadows area. Just at about this moment the sun was rising high enough to begin to warm the frost covered meadow, at least the parts of it that were not flooded by the high water of the Tuolumne. Overnight it had risen almost to the level of the bridge and was so high that after passing under the bridge a small portion split off and headed into the trees to the right of the main branch. In a few weeks this flooded area and its reflecting surface will be gone, and there will just be a meadow and people will hike though it.

The backlight comes across the shoulder of Mammoth Peak, the high point near the end of the long snow-covered ridge of Kuna Crest, which runs parallel to Lyell Canyon toward Donohue Pass and the Sierra Crest.

Alpenglow, Mammoth Peak

June 9, 2011 G Dan Mitchell Leave a comment

Alpenglow lights the face of Mammoth Peak beyond a small tarn near the summit of Tioga Pass, Yosemite National Park.

This was very close to the last exposure I made on this productive late-July day last year. After photographing for a few hours in the vicinity of Tioga Pass, I ended up right at the pass as the day came to an end. Braving hordes of mosquitos – comes with the territory! – I worked the area around the pass itself, building compositions out of juxtapositions of the water in the small meltwater ponds, shoreline meadow and boulders, grasses growing along the edge of the water, the surrounding pine forests, and the more distant peaks of Kuna Crest. In this photograph, what is very nearly the very last direct light of the day is bathing the slopes of Mammoth Peak, which still had a fair amount of snow on its flanks even in late July.

This scene posed a few technical challenges. First, there is obviously a great distance between the foreground granite boulder and the very distance mountain. I wanted the foreground to be in optimal sharpness, so I used a relatively small aperture to maintain sufficient sharpness on the far ridge. There was also a fairly large dynamic range in the scene, ranging from soft but direct light on the snow fields of the peak to the dark areas within the forest on the other side of the pond. I wasn’t certain that I’d be able to handle the full dynamic range in one exposure, so I made three – one longer exposure to get a bit more light from the shadows and another shorter one on the dark side to avoid blowing out the brighter areas of the sky. In post, I discovered that there was enough detail in the shadows that I could get everything I needed from a single exposure, though I had to do some work with curves to get create an image the conforms more closely to the way I saw the scene at the time.
