Abstract
The chemical reactions that take place in a photographic developer are discussed in detail. It is pointed out that, following the determination of a chemical formula that produces optimal photographic results, the concentration of every important ingredient of this solution may be held constant by the use of continuous replenishment and chemical control. After a discussion of the theoretical considerations involved, details are given for the establishment of picture negative, variable-density sound negative, and positive systems in use at the Paramount West Coast Laboratory.
