Photography - Pin-hole camera's

A Pin-hole camera is very simply a camera with no lens and a single very small aperture. In a very simple way of explaining it, is that it is a light proof box with a small hole in one side. The light from a scene is passed through this single point and projects an inverted image on a piece of photographic paper on the opposite side of the box. The smaller the hole, the sharper the image. A pinhole camera's shutter is usually manually operated because of the lengthy exposure times,and consists of a flap of some light-proof material to cover and uncover the pinhole.
