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.

Trees and Sunset Sky, Olmsted Point

July 7, 2011 G Dan Mitchell Leave a comment

Trees growing on granite silhouetted against a colorful sunset sky at Olmsted Point, Yosemite National Park.

This astonishing, magical light occurred just at and right after sunset on the evening of June 18, the day that Tioga Pass finally opened for the 2011 summer season. I earlier posted a vertical format photograph of much the same scene, though with slightly different light – the other photograph was made about a minute after this one and the conditions were changing very rapidly.

The photograph was made from the popular Olmsted Point overlook along the Tioga Pass Road (highway 120), with its well-known view of subalpine Tenaya Lake. Since I have recounted the story of this light in some detail in an earlier post, I’ll keep this description somewhat short, but here is the genera outline. Earlier in the evening I had come here to try to photograph Mount Conness with a long lens. Initially the light was very unpromising, but I observed some things that suggested the possibility of sunset light so I stuck around. Just before sunset, as the sun dropped near the horizon to the west, the light came from below to illuminate the thin, high clouds and produce an amazing color show.

To make the series of photographs of these trees I simply pivoted my tripod around from the direction it had been pointing, towards Mount Conness. The trees are somewhat sparse here since the granite domes and slabs cannot support many of them. The speed of light and color transition was remarkable. At one or more points, as the clouds picked up the sunset glow, the brightness of the light suddenly increased noticeably. The brightest color moved across the sky from east to west, and here the color was just beginning to diminish ever so slightly overhead as it continues to intensify to the west and closer to the horizon.

Last Light, Mount Conness

July 6, 2011 G Dan Mitchell 2 Comments

The final evening alpenglow illuminates the summit ridge of Mount Conness and the west face of Medlicott Dome in the Yosemite National Park high country.

This will be my final photograph of Mount Conness from the evening of June 18, the day that Tioga Pass Road opened this year and the day of one of the most spectacular Yosemite high country sunsets in recent memory. It will be the final both in the sense that I think I’ve now shared the best of the group of images of this sunset and in the sense that it was literally my final exposure of the evening.

The short back-story is that what started out as a fairly unimpressive evening (at least in the photographic sense) transformed over a short period into something extraordinary as the sun dropped to the horizon west of the Sierra and illuminated the clouds from below, creating rare and very special alpenglow conditions over a wide area of the Sierra. (During the week that followed quite a few people commented on this amazing light, which they had witnessed from locations as distant as Mono Lake on the east side and the Central Valley to the west.)

When I made this photograph the show was coming to an end. At this point the sun had already set a few minutes earlier – the exposure was made around 8:45 p.m. – and the light was low enough to require a six-second exposure. While it may seem like Mount Conness (the tallest peak near the left on the skyline) and other features are receiving direct sunlight, this is actually the remaining post-sunset glow in the western sky.

Trees in Silhouette, Olmsted Point, Sunset

June 29, 2011 G Dan Mitchell 1 Comment

Trees at Olmsted Point are silhouetted against a brilliantly colorful spring sunset sky, Yosemite National Park.

I think everyone should occasionally get to post a just plain gaudy color sunset – and this is mine. While photographing Mount Conness from Olmsted Point was my primary goal on this evening, I also had some opportunities to swing the tripod around and point at other things from time to time. This is about as close as I can come to capturing the nearly hallucinogenic color of the sky as the brightest cloud illumination was centered directly overhead and beginning to move off to the west.

The color saturation was so intense that I had to under expose this by at least a stop in order to avoid blowing out the red channel and in order to retain some differentiation among the various shadings of color as they transitioned from very pink/red through orange and purple and on towards blue.
