“One of the oldest camera forms is the Pin-hole, or “natural” camera. The pinhole camera was mentioned as early as Leonardo DaVinci in his Codex Atlanticus and Manuscript D. The term Camera Obscura or “dark room” was first used by Johannes Kepler who used the term to describe a dark room or box with a small hole used by artists to draw landscapes, it wasn’t until the 1850’s that the first photographic pinhole image was created.” Here’s how to make one for you digital camera.
