Composite Photographic Processes
The author traces in this paper the development of composite photographic processes, in terms of the patent history of the art, from its beginning to April 1, 1932. For convenience, the art is divided into three phases, namely: the mask process, the projection process, and the color-separation process. Each of these lines has evolved into several variants, the development of which is traced through the patent literature.
