Living in the San Francicsco Bay Area means getting familiar with fog. Fog can be annoying and dangerous, but it can also be beautiful. Fog has graced many outstanding photographs. Local photographer Simon Christen has upped the ante on fog photography. Using time lapse techniques and positioning himself before dawn at strategic vantage points in the Marin Headlands, and investing two years in the project, he has documented the flow of fog as a river. This is a meteorological documentary, and it is at the same time high art. See if you don’t look at fog with new eyes after seeing Christen’s video, titled Adrift. Be sure to expand it to full screen and have audio turned on.
