ABSTRACT:
Disclosed herein is an apparatus for developing photographic prints including a cabinet which houses a developing tank, a removable hood for covering the developing tank against the entrance of light, a print holding fixture mounted for rotation relative to the developing tank, and a plurality of containers or compartments for storing developing reagents and rinse water. The print holding fixture includes mounting units which are adapted to contact only the opposite outer edge portions of a print and hold it in a plano-arcuate shape with the image or exposed side facing inwardly. The cabinet includes a chamber which jackets or surrounds a major portion of the developing tank and holds warm water for tempering developing reagents and rinse water container in the developing tank. The developing reagent and rinse water containers or compartments are connected to the developing tank by individual conduits including intermediate portions which are located in the lower portion of the chamber and mounted in a coiled fashion so that the warm water tempers the developing reagents and the rinse water prior to their introduction into the developing tank. The apparatus also includes control valves for selectively admitting each reagent and the rinse water into the developing tank and a drain valve for draining the developing tank so that, after installation of a print or prints on the holding fixture, the entire development process can be performed in a lighted room.
