High Speed Photography and Micrography

Abstract

A brief review is given of those methods of high speed photography that are or may be useful for micrography. When we try to record an event at a high lateral magnification, the image is moving much faster than the object, so that exposure times must be proportionately reduced. Moreover, at high lateral magnification, the available light flux per unit area of the photographic emulsion is in general much less. These two effects make high speed micrography the most difficult branch of high speed photography. In some ranges of speed and magnification, relatively conventional equipment is adequate, but there is no single technique that will do all that we want.
