Photographer Simon Christen spent two years compiling footage of San Francisco‘s famous fog for this 4.5-minute, piece of Zen, time-lapse video. His “love letter to the fog of the San Francisco Bay Area” was written during pre-dawn, 45-minute hikes into the Marin headlands to capture the fog gliding over the hills and under the Golden Gate Bridge. The result is quite beautiful. The fog tumbles over the hills like a waterfall, rolling like ocean waves as it streams toward the city. The video is scored with dreamlike music by composer Jimmy LaValle, making it a therapeutic tribute to the soft forces of planet earth. Indeed, the San Francisco Fog itself was impressed with the video, tweeting that it was the “most stunning video of me you’ll ever see.”
