Photo: Giant Camera, Cliff House, San Francisco

The Giant Camera is a walk-in camera obscura, based on a 15th century design by Leonardo da Vinci. A syurvivor from the now-disappeared "Playland at the Beach" amusement park, It produces 360 degrees of live Images of the Seal Rock Area. It was removed during the recent renovation of the Cliff House, then re-installed very close to its original location - but has not reopened to the public since.
