Pinhole camera, 1981.

A pinhole camera made from a square biscuit tin. Adequate photographs can be taken without expensive cameras. Any light-tight container with a pinhole at the front, to act like a lens, can be used to focus an image onto a piece of film fastened to the back of a box. The early cameras devised by William Henry Fox Talbot (1800-1877) were effectively pinhole cameras with a lens, as was the famous Kodak Box Brownie which brought photography to a mas market in 1900.
