Alcatraz Island, San Francisco Bay Fog

December 26, 2010 G Dan Mitchell Leave a comment

Alcatraz Island is almost completely obscured by San Francisco Bay fog drifting beneath blue sky.

This is another of what I sort of think of as my “barely there” photographs, in which I work with subjects that are almost completely obscured by fog, mist, rain, or clouds. Some of my Yosemite Valley photographs from a rainy weekend near the end of this past October are in the same category.

You can experience an astonishing range of atmospheric conditions in and around San Francisco Bay. The patterns at this time of year (the very end of fall, and more like winter conditions) are quite different from summer. As often as not, the fog in the winter comes from inland rather than drifting in through the Golden Gate, and it is more related to the tule fog that can sit in the Central Valley during the winter, sometimes for weeks. On the other hand, after the passage of a winter storm (which brings its own impressive conditions) the winter air over the Bay can be crystal clear. And frequently the conditions can change rapidly, as was the case on this morning. When I arrived in the Marin Headlands above the north end of the Golden Gate Bridge before dawn, I was initially a bit disappointed that the conditions were too clear! Except for a bank of clouds right above San Francisco (the subject of some other recently posted photographs) the rest of the Bay was almost completely clear. But then, at first imperceptibly and then very quickly, fog began to condense out of the air above the bay. In a short period of time subjects that had been clearly visible were completely obscured. Within moments after making this photograph, Alcatraz was not longer visible.

Coit Tower, Fog

December 23, 2010 G Dan Mitchell 3 Comments

Here is one more in this series of photographs of the San Francisco waterfront and downtown areas in brightly back-lit, early morning conditions with the City nearly obscured by drifting fog. All of the photographs in the series were made from a location near the north end of the Golden Gate Bridge, just a bit up the road into the Marin Headlands. Like several of the others, this one was shot with a 400mm focal length lens, pointing almost directly toward the rising sun. For some of the exposures I had to stand a couple feet in front of the camera, at the maximum extension of my remote release cable, and carefully position my hand to shade the front element of the lens.

Here the fog has almost completely obscured Coit Tower at the top of Telegraph Hill. If you look very carefully to the left of Coit Tower you can barely make out the ghostly image of the top of one of the towers of the San Francisco Oakland Bay Bridge. It was my good fortune that a slightly less opaque section of the drifting fog momentarily framed the summit of Telegraph Hill.

San Francisco Skyline, Light Beams

December 21, 2010 G Dan Mitchell 2 Comments

Beams of light from brilliantly lit clouds send beams of light past downtown San Francisco buildings and toward the waterfront.

Anyone who knows San Francisco might be wondering about this light – and I wouldn’t blame them. These were really unusual conditions. Believe it or not, the photograph was made very early in the morning, perhaps a bit less than a half hour after sunrise. Which begs a couple of questions: why is the light coming from the right (west to southwest) at dawn? And, why does the light seem to be coming from such a high angle?

The light beams are not direct sunlight. The sun is actually far to the left of the frame and very low in the sky. Its direct light was blocked by intervening fog clouds. As the clouds moved from left to right, thinner areas in the cloud cover were struck from behind by the very low angle sunlight coming from the left and set aglow. It was the brilliant light from these areas of backlit clouds that cast the light through the mist and between buildings. What you cannot see in the still photograph is that as the clouds moved the beams of light slowly swept from right to left. From moment to moment the light beams would angle from right to left, then straight down, and then left to right.

Another amazing thing was that I appeared to be the only person out making photographs of this…

Mushrooms, Redwood Log

December 18, 2010 G Dan Mitchell 4 Comments

Winter mushrooms grow on a redwood log at Muir Woods National Monument.

Yesterday I decided to squeeze in a quick shoot in the Muir Woods area on a relatively nice day before what promises to be a week of substantial rain. So I was on the road early, stopping at the north end of the Golden Gate Bridge to photograph the San Francisco Bay at sunrise before continuing on to Muir Woods. I arrived pretty early – I know I’m there early when I get the very first parking space closest to the entrance!

This is a beautiful time of year in the redwood forest, but there seems to be a smaller number of visitors. I suppose the wetness may keep them away – there is mud and water everywhere – and not everyone is willing to deal with the cold. The main grove at Muir Woods sits in the bottom of a canyon that doesn’t get a whole lot of sun this time of year, especially very early and late in the day. Combine wet with cold and low light… and you can understand why it was a fairly quiet morning there, with only a few other people wandering about.

I know that winter is the mushroom season in places like this, but I was very surprised by the number of mushrooms growing there yesterday and my the astonishing variety of types. There were the large curving brown ones (sorry, I’m not a mushroom ID expert, to say the least!) clustered in the upper area of this shot, the brightly colored yellow ones, tiny white ones, and many other shapes and colors and textures. I wish that I could have stayed longer to photograph more of them, but I think I’ll try to return after the current cycle of storms ends.

I’ll add a couple of photographic observations here, too. First, this is another shot that demonstrates, I think, the usefulness of the 70-200mm zoom lens. Working here at close to minimum focus distance, the longer focal length gave me a bit of working room and still provided a nice background blur. Second, the redwood forest is a very dark place! I don’t know how you could shoot these subjects handheld – this shot used a 6 second exposure!
