Photographic chemistry

Abstract

A photographic chemistry comprised of a solution containing a mixture of different chemicals which cooperate to minimize the need for long film exposure times to achieve high film quality and contrast. The photographic chemistry includes a number of alkalies in a pH range from about 8 to 14, a developer in solution with the alkalies, a solvent mixed with the alkalies and the developer, a modified alkanolamide in solution with the alkalies, the developer and the solvent, and a hydrotrope mixed with the modified alkanolamide. Other chemicals that can be used in the photographic chemistry include an emulsion penetrant, a cleaner for various components of film processing equipment, a chelating agent, and an enzyme to enhance the reactions of the various chemicals in the photographic chemistry. A specific mixture of chemicals is disclosed.
