Glacier Point and Ground Fog in Ahwahnee Meadow, Autumn

November 19, 2010 G Dan Mitchell 8 Comments

Thin morning ground fog floats above the dry autumn grasses of Ahwahnee Meadow below the granite cliffs of Glacier Point, Yosemite Valley.

During the cooler and wetter months of the year, ground fog often forms in the meadows of Yosemite Valley. Ahwahnee Meadow is one of the places I like to photograph these conditions, and since this was the morning after a damp and rainy day, I arrived here very early in anticipation of conditions that might produce the fog. It was very cold when I arrived, certainly below freezing by at least a few degrees. At first the fog was much denser and a bit deeper. I have photographs from this earlier pre-dawn period when a herd of deer passed through the meadow. Eventually, as the sun rose high enough that the light beams began to clear the mountains to the east of the Valley, the first light began to strike the upper slopes and walls of Glacier Point. As this happened and the air began to move and the temperature stopped dropping, the fog began to thin. This photograph was made shortly before the fog actually dissipated completely, and thin streamers of mist are broken up by clearer areas.

I have to admit that I do not know what the foreground plant is. (Hint: I won’t mind even a tiny bit if someone wants to write and tell me! :-) Cottony tufts are found at the top of long stems, growing out of odd shaped pods. I shot this with a very wide angle lens so that I could include some of this foreground foliage and the fill width of Glacier Point.

On a technical note, this image incorporates a blend of two exposures. Portions of the sky at the left side of the frame were very bright, while much of the rest of the scene was in shade and a lot darker. Almost the entire frame is from the 1/15 second exposure, but I have manually blended in a bit of the 1/40 second exposure in the area of cloudy sky at upper left in order to retain a bit of detail there. Also, though it should be obvious, this was shot with an ultra-wide angle lens – a 17mm focal length on a full frame DSLR. If you are at all familiar with this location in the Valley you will recognize that this is a bit of an unusual view.

North Lake and the Sierra Crest, Fall

November 16, 2010 G Dan Mitchell 1 Comment

Brilliant gold and red fall aspens ring the upper shore of North Lake as the Sierra Crest towers above.

Somewhat past the “golden hours” of first light I investigated a hill above this lake as a possible shooting location. Because this was a morning of mixed clouds and sun, the time for good light was more extended than it might otherwise have been. The clouds began thicker and gradually began to thin, and as they did so the mixed sun and cloud shadows moved continually across the landscape, spotlighting different parts of the scene. This was one of those situations that puts the lie to the notion that the landscape is a fixed and static thing – from my perspective the entire scene was in a constant state of flux and photographing it required full attention. Here most of the shadows had cleared from the scene, with the exception of some over the foreground lake and a few scattered among the peaks, and beams of light slanted into the scene to light up the grove of brilliantly colorful fall aspens.

Aspen Color, North Lake

November 15, 2010 G Dan Mitchell 7 Comments

Colorful autumn aspen colors surround the shores of North Lake with the Sierra Crest beyond.

I should probably hand out sunglasses and an Official Icon Alert warning with this one. Yes, it is that North Lake.

Later on this morning, after shooting elsewhere around the lake in the early hours, and after the workshop shooters had mostly moved on (after all, the good light was gone… ;-), I decided to cross the outlet stream and see about climbing up a hill above that lake that I had been thinking about. I found an easy trail along the side of the lake, but then had to more or less bushwhack my way up the slope to get above the tops of the very red lakeside aspens, which is no easy task when carrying a large photo pack and a good size tripod. (Once up there, I discovered a very easy trail going straight to my position. Sigh.)

Although it was no longer the “golden hour” and the morning was well along, there were scattered clouds. These shadows from these clouds moved rapidly across the landscape, sometimes producing almost uniform shade and sometimes lighting up some features while leaving others less visible. When I see conditions like this I often imagine the perfect positioning of the clouds and the light effects they produce – some primary feature caught in the spot light of a beam of sun, others in sunlight muted by thin clouds, and any spots that happen to be a bit too bright and distracting miraculously muted by a perfectly placed shadow. Yeah, right. But if I watch and wait long enough, something interesting almost always happens, and sometimes the moving clouds do momentarily solve composition and exposure problems. Here, the light on the bright red trees in the foreground is momentarily diminished by a passing cloud shadow and the shoreline trees are in sunlight… and the big cloud at upper left is reflecting on the surface of the water just beyond the foreground trees.

Photographer, Sabrina Basin

November 14, 2010 G Dan Mitchell 15 Comments

I wandered out onto this ridge above Sabrina Basin, a spot that I know for its unobstructed view of the valley and the peaks of the Sierra crest above Sabrina Lake, far up the canyon. I had my eyes on some rocky benches that run along the top of the ridge As I approached I saw that I wasn’t the only photographer with this idea. As I crossed the rocks toward the overlook, he was working my intended camera position, so I decided to sit back and let him finish. (The ridge wasn’t wide enough for both of us to work together there.)

As I waited, I thought there was something interesting about his position above the valley, his concentration on shooting, his all-blue outfit (shirt and jeans, on a cold and rainy day!), and that wide brimmed hat. So I decided to make a few photographs of him. We barely talked at all. I hoped to get his name, but that didn’t happen. The best I was able to do was give him a card, and offer him a copy of the photo if he contacted me. Never heard from him…
