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.

Stairs, Person Walking

July 29, 2011 G Dan Mitchell 2 Comments

A person walks past the bottom of a stairway along Stockton Street, San Francisco.

When I posted a color version of this photograph a week or so ago I mentioned that there was also a black and white version – and that I was up in the air about which I prefer. I’m still not certain, though I’m leaning more towards this monochrome version. While there are some aspects of the subtle colorations in the other version that I am hesitant to give up, I think that the angles and forms and masses of dark and light may be more the focus in this version.

Since I told the story on the original post I’ll keep it short here. I was in the Stockton Street area of Chinatown in the morning and had crossed the “bridge” at the termination of a dead end alley that sits above Stockton. There were two stairways down to the street level where Stockton emerges from a short tunnel. As I went down the stairs I thought that the angles and the light in the stairwell looked interesting as forms and was working out a composition or two when the figure walked through the frame and I reacted quickly to make a photo that is quite a bit different from what I was thinking of when I started.

Rocks and Fog, Point Lobos

July 27, 2011 G Dan Mitchell 2 Comments

A rocky peninsula drops into the ocean on a foggy morning at Point Lobos State Reserve.

On this morning it was foggy and drizzling at Point Lobos and there was a surprising amount of surf for a summer morning. When I arrived shortly after the park opened, there were few other people about. With the moving water and the low light conditions, I decided that this was a good time to do some work with long daytime exposures, so I got out my 9-stop neutral density filters and went about looking for compositions.

After shooting down closer to the water in the cove to the left of these rocks, I wandered up a trail along the shoreline that took me to a point that was a bit higher above the water. As I looked back I saw that the rocks that defined the cove that I had been shooting appeared to head straight out into the water towards a distant peninsula and then submerge – a rather different take on this feature.

By using this filter I was able to get an eight-second exposure in this light. Longer would have been better, but the light was beginning to come through the fog a bit and I didn’t have much choice. With an exposure this “short” I had to be a bit careful about timing the shots, trying to get the right amount of water breaking over the rocks.
