 The simplest kind of camera - perhaps one that you have made yourself - consists of a lightproof box, with a small hole made in one side and a screen or a photographic film on the other. Light rays passing through the hole generate an inverted image on the rear wall of the box. This simple model for a camera is commonly used in 3D graphics applications.
