This mesmerizing time-lapse of San Francisco's fog took two years to make
As a native of the San Francisco Bay Area, I'll admit that I dread seeing the infamous wall of fog that can make summers in San Francisco so chilly pass over the city's hills and block out the afternoon sun. Filmmaker Simon Christen apparently feels otherwise, as he spent two whole years (!) documenting the fog as it drifted in for a time-lapse video called Adrift.
Simon describes his video as "a love letter to the fog of the San Francisco Bay Area," and creating it required him to keep close watch on the weather to make sure conditions were "just right." As he describes:
"The weather conditions have to be just right for the fog to glide over the hills and under the bridge. I developed a system for trying to guess when to make the drive out to shoot, which involved checking the weather forecast, satellite images and webcams multiple times a day. For about 2 years, if the weather looked promising, I would set my alarm to 5am, recheck the webcams, and then set off on the 45-minute drive to the Marin Headlands."
