Description
The Camera Obscura in San Francisco is a large-scale camera obscura and is listed on the National Register of Historic Places. It is located near the Cliff House restaurant perched on the headlands on the cliffs just north of Ocean Beach on the western side of San Francisco, California. The Camera and restaurant are currently owned by the National Park Service as part of the Golden Gate National Recreation Area. It was added to the National Register of Historic Places on April 20, 2001.
The San Francisco Camera Obscura projects an image onto a horizontal viewing table via a reflected image from a viewpoint at the top of the building. A metal hood in the cupola at the top of the building slowly rotates, making a full revolution in about six minutes, allowing for a 360° view around the building.
Light enters the building via an angled mirror in the metal hood. It then passed through a lens with a 150 in. (381 cm) focal length and is projected onto a parabolic white "table" in a black room. The origin of the lens is uncertain but it appears to have been part of a telescope, likely manufactured by the Clark Lens Company of Cambridge, Massachusetts.
