San Francisco’s fog is almost as iconic as the city’s Golden Gate Bridge. The foggy weather—a blanket of coastal low-lying clouds—drifts in mainly during the summer months, and has captured the attention of photographer Simon Christen. Over the course of two years, Christen spent many an early morning hiking up to the Marin Headlands, a hilly area with expansive views of the Bay Area.

A collection of his favourite shots, the short film Adrift is Christen’ love letter to the fog of San Francisco. It’s quite magical, check it out below.
