Spring Torrent, Cascade Creek

May 15, 2011 G Dan Mitchell 2 Comments

A torrent of water from melting spring snow rushed through a rocky section of Cascade Creek, Yosemite National Park.

During the early part of the seasonal spring snowmelt runoff, Cascade Creek is transformed into a wild and raging torrent as the lower elevation snow in the upper portion of its drainage begins to melt quickly. Contributing to the spectacular effect is the very steep path the creek follows down the walls of the Merced Canyon before it makes one final leap over a waterfall and then joins with the main Merced River.

This bit of creek is another of those places in the Sierra that I have come to know very well. There are certain places where I like to say that I know individual rocks and trees, and this is one of them. I photograph here several times each year during all seasons and in all kinds of light. But my favorite is the early morning spring light, before the sun rises high enough to directly illuminate the creek bed, when the creek is flowing madly and twisting and turning around and over boulders.

Dogwood Bloom and Leaves

May 12, 2011 G Dan Mitchell 10 Comments

An early dogwood blossom and leaves in Yosemite Valley, California.

This is another plant that I’m on a first name basis with. I know this particular dogwood rather well, having first been attracted to it one fall while walking along the north side of Yosemite Valley looking for leaves against rock. At that time the fall-color leaves of this dogwood tree were draped across the top of a low, flat boulder. When I’m in this part of the Valley, I often walk past this tree to see what it is doing. On this first weekend of May, the tree was just getting its first blossoms of the spring season, and I was able to clamber up on top of the boulder, set up my tripod, and make a few close-up photographs of the flowers.

I originally figured it would be a color photograph but as I worked on it I started to think it might be interesting in black and white, too. (You’ll get to decide – the color version will appear tomorrow.) Besides having to wait for the slight breeze to pause so that I could make a 1/8 second exposure, another challenge was the dynamic range between the bloom and the rather dark background. I tend to slightly underexpose the highlights, since digital capture is not kind to over-exposed whites. Then I work in post to bright the brightest parts back up to where I think they should be, but without letting anything blow out.

For dogwood fans, the “word on the street” had been that these flowers were coming along a bit later than usual this year. But on this day it seemed like they were suddenly starting to appear in many of the usual places in the Valley. I’m expecting them to peak between now and perhaps a week or so from now, and later on at higher elevations. One potential wrinkle is the possibility of snow in the Valley on Sunday!

Update: There is also a color version of this photograph.

Young Tree and Granite Wall

May 11, 2011 G Dan Mitchell 2 Comments

A young tree grows against a granite wall along the north side of Yosemite Valley.

This tree (and its nearby oak partner) and I have become good friends over the past few years. I first photographed it in the fall some years back, though the oak made a better shot at that time given its fall color leaves. But every time I walk along a certain area under the cliffs on the north side of Yosemite Valley I check in here to see what the light is doing.

During the first weekend of May I was in the Valley for photography and to visit the reception for Michael Frye’s exhibit at the Ansel Adams Galley. After spending an enjoyable hour and a half or so viewing Michael’s prints and meeting and talking with a wonderful group of photographers and photography enthusiasts at the Gallery I left to go wander a bit and make some photographs. When I came to this spot, clouds were starting to appear in the late afternoon sky above the Valley. This is a kind of ideal light since these conditions soften but don’t completely destroy the sunlight, and diffused light gets down into the forest and fills out the shadows.

I love the texture of these huge blocks of flat granite, covered with lichen. I like the visual quality of this rock, but I also like the physical quality of it; this probably dates back to a time some years ago when I was a rock climber for a few years. So while the tree seems like the main subject here, the rock surface is for me just as important.

Redwood Trunk, Detail

May 5, 2011 G Dan Mitchell Leave a comment

Detail view of the convoluted textures of the bark of a coast redwood tree, Muir Woods National Monument.

I’m fascinated by the patterns of tree trunks and bark, and I often try to find ways to make photographs of the thick and rugged bark of coastal redwoods – but not always with a lot of success! The subject is trickier than it seems at first. Even during the daytime these forests can be quite dark – and occasional beams of direct light pose their own problems along the lines of harsh shadows. When shooting close up, relatively small apertures are needed since some amount of DOF is required to get the closest parts of the thick bar, and the deeper parts along the frame edges decently in focus. Low light and small apertures means long exposures, and even a bit of air movement will move leaves, bits of grass, or (in the case of this photo) spider webs. And when a bit of interesting filtered light does make it down through the forest canopy, it is often there and gone within a few seconds. (On this same day I came across a beautiful shadow on the side of one redwood that included the shapes of some nearby alder trees. It was wonderful! It was also gone 10-15 seconds later when I got my camera into position!)

I photographed this bit of bark shape and texture along the main trail at Muir Woods on this late-April morning. As is my usual plan, I had arrived very early – before the park actually opens – and was able to wander around without the typical crowds that appear once the post-breakfast tour buses arrive from nearby San Francisco. In this spot it was quite dark, but there was just a bit of filtered and reflected light to bring out the textures and colors of the redwood bark.
