Pond with Boulders and Trees

August 24, 2011 G Dan Mitchell 2 Comments

A small pond reflects trees and glaciated boulders, Yosemite National Park.

This is a little location that I’ve returned to since I first discovered it a few years ago when I made a random stop along Tioga Pass Road to photograph some fog, looked away from the road, and saw a faint trail leading off into a little valley that looked to be full of rocks. Later I returned and wandered out on the trail and discovered a surprising landscape with glaciated granite, small pools, open forest, and small meadows. The first time I photographed there I had little time, so it ended up being more of a scouting visit than a shoot. However, this summer I planned to reserve part of a morning to wander back up this trail during the time when the light would still be good.

The pools here are almost completely still. The water is flowing, but not much, especially in the small granite rimmed pools like this one. The light was just barely beginning to filter down through the trees, so I had to be a bit careful to avoid hot spots where the sun shone. I’d share where this spot is, except that if you think about what you are passing as you drive along Tioga Pass Road, and occasionally stop and look around, you can probably find your own little spots like this one.

Breakwater, San Francisco Bay

August 19, 2011 G Dan Mitchell Leave a comment

Anchored ship and ship yard cranes of the port of Oakland beyond a breakwater, San Francisco Bay.

I made this photograph on one of my summertime San Francisco visits on which I head up there on the train very early in the morning, and then I walk wherever my nose leads me, making photographs. On this visit I left the train station and ended up crossing a bridge to the inlet behind AT&T park, sometimes called “McCovey Cove.” From along the far side of this inlet I could see across the San Francisco Bay to the towering cranes at the port of Oakland. They were backed by a fog bank that completely obscured the city of Oakland and all but the very tops of the East Bay Hills.

This morning light coming across the Bay can be very special. As it often shines through the moisture laden air over the water and sometimes through clearing fog, it can take on a luminous glow and can even be almost too bright to look at. This was that sort of morning, so I let the sky exposure go as close to white as I could and still retain some sense of the thick air. The dark object at the left is a concrete breakwater outside the entrance to South Beach Harbor.

Flooded Meadow Near Greenstone Lake

August 17, 2011 G Dan Mitchell 2 Comments

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

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.
