Clearing Fog, North Tower of the Golden Gate Bridge. San Francisco, California. September 26, 2010. © Copyright G Dan Mitchell – all rights reserved.

Morning fog clears from the North Tower of the Golden Gate Bridge, San Francisco, California.

Last week I made a quick trip north of San Francisco to photograph in the morning at Muir Woods National Monument in the Golden Gate National Recreation Area. My habit is to be on the road early enough to arrive at Muir Woods before the crowds arrive, and this almost always means that I cross the Golden Gate quite early in the morning, sometimes at dawn and sometimes a bit later. As I go across the bridge I keep my eyes open for special or unusual conditions – I no longer stop every time, but I do if the scene looks more interesting than usual.

This morning was unusual. It was extremely hot and dry inland, yet the offshore fog bank was making a valiant (and ultimately unsuccessful) effort to push its way through the Golden Gate past the bridge. The fog was not deep and it could only sustain itself where there was plenty of water or as it passed directly over the hills on either side of the entrance to the Bay. This meant that light was coming through the fog and it was intermittently coming and going along the edge of its incursion into the warmer air. So, I stopped.

This photograph looks back across a section of the bay that is fog covered and brightly back lit by the morning light, with the higher fog trying to push across the shoulder of the hills of the Marin headlands with the distant view of the San Francisco skyline beyond.

On a technical note, I used a 50mm prime lens for this photograph – the Canon EF 50mm f/1.4. I switched to the prime from my more typical zoom for several reasons. First, this composition seemed to work with the 50mm focal length. Second, this 50mm prime is a really excellent lens for landscape and similar work, providing outstanding resolution at the apertures typically used. Finally, I had the luxury of not having to work quickly – so I could rely on a prime with the “right” focal length rather than working with the zoom.
