Late-season snow fields are reflected in the pond of a flooded alpine meadow near Greenstone Lake, Sierra Nevada.

During this year of heavy and late winter snowfall, there is still a surprising amount of snow in the Sierra Nevada high country. In the upper portion of this image you can see large snow fields (with much larger ones higher on the slope and out of the frame) at that base of this talus slope at around 10,000+ feet of elevation. During a more typical year, there would still be a few scattered snow fields, but nothing like we see this year. And because there is still so much snow, the plants that would normally be well-developed by now are still just emerging, and the creeks and ponds are overflowing, the meadows are flooded… and the mosquitos are having a field day!

This little pond among the boulder-filled meadows near Greenstone Lake at the far end of Saddlebag Lake was still overflowing with snowmelt water that reflected the extensive snow fields still on the talus field beyond. To get to this spot – in mid-August! – I had to cross a number of still frozen snow fields, follow trails that were flooded in places, and pick my way carefully across waterlogged meadows. It is going to be a short summer season in the high Sierra, but as a compensatory bonus we may still see wildflowers all the way into September.

Sunset and Moonrise, Kuna Crest

Sunset and Moonrise, Kuna Crest. Yosemite National Park, California. August 10, 2010. © Copyright 2011 G Dan Mitchell – all rights reserved.

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.

Alpenglow, Trees, and Granite – Upper Young Lake

Alpenglow, Trees, and Granite – Upper Young Lake. Yosemite National Park, California. September 14, 2010. © Copyright 2010 G Dan Mitchell – all rights reserved.

Alpenglow light on trees growing among granite boulders below glacially carved cliffs at Upper Young Lake.

This is one of my favorite locations in the Yosemite back-country and, in fact, in the entire Sierra Nevada range. This beautiful sub-alpine basis contains three lovely lakes and is surrounded by varied terrain that includes distant views, peaks and ridges towering above, lodgepole pine forests, meadows small and large, and an open view to the west that often provides stunning light late in the day.

As is usually the case, I was camped at the lower Young Lake – this time for several days of photography – and I had headed to the upper lake late in the day to do some evening photography. I have photographed there quite a few times, but I still haven’t come close to exhausting the photographic potential of the place. On this evening I knew that I wanted to be ready to photograph the golden hour light, but I was also interested in the smaller groups of trees that grow among the granite boulders and I wanted to see what might develop as alpenglow struck the glacial slopes above the lake.

There is a small, fun twist to the story of this visit to Upper Young Lake. I took a semi-cross-country route to the upper lake from my camp at the lower lake, and because I knew that I’d be returning alone in deep twilight or even after dark, on the hike up I was concentrating intensely on fixing a series of landmarks in my mind for the return hike. I was so single-minded about this that I made it all the way to the lake and my first intended subject (a small shoreline tree) without looking around much. It was only a moment after arriving that I got out of focus-on-the-route mode and looked around. I had walked right past the campsite of a couple of photographers without even seeing them, much less saying “hi.” Turns out that the photographers were John Sexton and Anne Larsen. After exchanging greetings and conversation, I went about my business of shooting along the edge of the lake. (If I recall correctly, John was shooting nearby as I made this exposure.)

Ellery Lake

Early season morning light on Ellery Lake near Tioga Pass.

I made this photograph on the same early-season morning on which I made the vertical format photograph of the same scene that I recently posted. Ellery Lake is alongside highway 120, the “Tioga Pass Road,” just beyond the eastern boundary of the park and the Sierra crest. To be completely forthcoming, I made this photograph from the side of the road! (The many individuals who know this area well, and who have probably stopped to look at the same scene, already knew that…)

To briefly recap, the road here curves around the upper end of the lake above this small bay. Looking across the bay, the rocky edges of the lake are visible along with the steep talus slopes ascending to the peaks around Mt. Dana beyond. The spot has a natural beauty in terms of the forms of the landscape, but I think it is difficult to photograph as a whole – the light is the tricky thing. The earliest morning light is block by high peaks to the east and the late afternoon light goes quickly from sun to shade as the sun drops below ridges behind the camera position, and this light can be fairly flat since it comes from directly behind. This photograph was made in the morning, but not close to sunrise at all – it was two or three hours later. Even here the scene isn’t without technical challenges, especially from the dynamic range that spans from the shadows behind backlit rocks and trees to the very bright snow fields at upper right.
