The Camera Obscura is basically a pinhole camera, but instead of projecting it’s image onto photographic paper, it is often projected onto frosted glass or even on to the wall of a room. Originally used for drawing (tracing), it is the precursor to the first camera.
Located in San Fransisco, the giant camera obscura projects an image onto the wall of the inside of the building. It was built in 1946 and continues to be a tourist attraction today.
