The camera obscura is an optical device used, for example, in drawing or for entertainment. It is one of the inventions leading to Photography. The principle can be demonstrated with a box with a hole in one side (any sized box from matchbox to room-sized or even larger) Light from a scene passes through the hole and strikes a surface where it is reproduced, in color, and upside-down. Camera is Latin for “room” and Obscura is Latin for “dark.”
This Camera Obscura is located in San Francisco, CA directly in front of the Cliff House restaurant on the Pacific ocean. It is a rare device, based on a 15th century design by Leonardo da Vinci. It produces 360 degrees of spectacular Live Images of the Seal Rock Area. It is also listed in the National Register of Historic Places.
