Greenstone Lake, Morning

August 18, 2011 G Dan Mitchell Leave a comment

Early morning light on Greenstone Lake and surrounding trees and rocky terrain.

Greenstone is a relatively small lake just beyond the upper end of Saddlebag Lake, which is itself located just east of the Sierra crest and Yosemite National Park in an area dominated by Mount Conness and the tall ridge on which it stands. I had arrived before dawn at the Saddlebag Lake parking lot so that I could be on the trail before sunrise. Rather than giving in to the temptation to pay for a “water taxi” ride to the other end of the lake, I took the trail along the left shore, and arrived at Greenstone Lake just about the time that the first direct light was making its way down to this lake and the surrounding rocky hillside.

In this wet year with its late arrival of summer conditions, everything was still very wet around the lake and the meadow plants were still green and growing. (In dry years they start to finish up their growth spurt and begin turning brown by this time.)

I think this lake is a bit tricky to photograph in morning light. The light could be lovely at sunrise, but it would still be well up on the high ridges above the lake. It takes a long time for the sun to get high enough to rise above the ridge leading to Tioga Peak, and by that time most of the early morning warm light quality has given way to more typical daytime light. There were a few challenges in this photograph. They included trying to figure out how to find a workable composition in such a complex scene that was made even more complex by the reflections in the water. I think the triangle of rocky terrain in the upper half of the frame may help with this. The light posed several problems, mainly related to the very large dynamic range between the bright rocks and the shaded areas of forest at upper right. The light color was also tricky – because the shadows tend to be much bluer in a photograph than your eyes register when you are there, I had to mute the very blue quality of the shadows. This was done partly with an overall adjustment to color, but some additional work had to be done directly on the shadows.

Eastern Sierra Nevada Near June Lake

August 16, 2011 G Dan Mitchell Leave a comment

Trees ascend sage-covered hills toward the Sierra Nevada crest near June Lake, California.

Near highway 395 in Mono County, the main north-south route east of the Sierra crest, these open stands of large conifers ascend from the high desert sagebrush country towards the peaks of the Sierra crest, which rise much more abruptly on this side of the range than on the gentle west side. The tall ridge is above the June Lakes resort area between Mammoth Lakes and Lee Vining.

While my primary goal on this trip was to photograph in the Yosemite high country along Tioga Pass Road, smoke from a wildfire near Glacier Point in the park was drifting over the Tuolumne area and creating a lot of very non-photogenic haze. I had a hunch that by dropped over to the east side of the range I might be able to get away from the smoke or at least find areas where it wasn’t so thick. The smoke was still affecting the light near Lee Vining, but I didn’t have to drive too far south to get out of its path, though even here there is a bit of haze increasing the effect of atmospheric recession.

Sunset and Moonrise, Kuna Crest

August 15, 2011 G Dan Mitchell Leave a comment

The nearly- full moon rises above the sunset light on Kuna Crest, Yosemite National Park.

Kuna Crest runs up Lyell Canyon between the Lyell and Dana forks of the Tuolumne River with the Sierra crest at one end and Mammoth Peak at the other. (Mammoth Peak is the large peak straight in front of you as you top Tioga Pass entering Yosemite National Park.) This ridge can catch great sunset light during the summer, and as I came down from the pass, heading back toward my camp at Porcupine Flat, and saw the almost full moon appearing over the shoulder of the ridge I decided to quickly stop and make a few exposures as the last light was about to leave the forest and soon after the peaks.

If you have tried photographing a scene that includes the moon in the early evening you know that the exposure is a tricky thing. The moon is lit by daylight, so it isn’t too surprising that the “correct” exposure for the moon is close to a normal daytime exposure. But that is not the right exposure for the rest of the scene, which turns out to be quite a bit darker than daylight at this time of day. In this scene things were even more complicates as the very saturated red colors on the ridge were quite “hot,” while the foreground meadow and forest was in shade and both darker and cooler in color. Basically, the dynamic range between the moon and the foreground was too large for a single exposure… so I made several.

At the time of exposure I thought that I might need as many as three component images in the final photograph – they would be one exposed for the bright ridge and sky, one exposed for the rather dark and shadowed foreground, and possibly a third that correctly exposed the moon. To be on the safe side I bracketed four exposures. When I began to work on the image I figured out that in this case I could construct a final “believable” image from two exposures if I was careful and could make some additional adjustments during post.

This is an example of a shot in which the use of a graduated neutral density filter could have been problematic, but where exposure blending could work very well. (“Exposure blending” is one term for the process of manually combining two component exposures using masked layers in Photoshop. No, it is not the same thing as HDR photography.) One of the things that would have been quite tricking using graduated neutral density filters is that the division between the brighter upper half and the darker lower half is not linear. Instead, the roughly follows the curved boundary between the lower meadow and dark trees and the still sunlit trees and the peak and sky.

Tree and Granite, Pywiack Dome

August 5, 2011 G Dan Mitchell Leave a comment

A weathered juniper tree grows high on the granite face of Pywiack Dome, Yosemite National Park.

This is another “take” on the same juniper tree high up on the slopes of Pywiack Dome that was seen in another photograph of this area that I posted earlier this week. I went through a process of “refining” the photograph that I described in the earlier post, and this was the interpretation that I came up with right before the landscape orientation version that I posted earlier. Unlike that photograph, this one frames the area of the dome containing the tree more tightly.

The color balance is a bit different in this one, also. I thought about that quite a bit, at first feeling that the coloration should be essentially identical since the images were made at about the same time and include some of the same subject matter. But the more I thought about it – and the more I experimented with the results of trying for uniformity – the more I felt that the two photographs are different images and that different interpretations make sense.

These trees never cease to amaze me. I often come across what are evidently very old trees that seem to grow almost straight out of solid rock, and only a closer inspection reveals that roots have grown tightly into small and unlikely cracks and weaknesses in the granite. That this tree should have managed to take root half way up the side of this large dome is even more amazing, much less that it managed to avoid growing into the stunted and twisted sort of shape that is so common among such trees.
