Paper Abstract

As first indicated by Otto Schade 1 and now commonly acknowledged, the formation of an optical image results when a set of random events is sampled over a finite space for a finite time. Silver halide grains do the sampling in film image formation by absorbing light and "remembering" it for extended periods of time. With the human eye, sampling is done by the individual rods and cones on the retina and the memory or exposure time is on the order of a tenth of a second.
