Process for developing photographed film and for printing images through

Abstract

A process for developing a film having one or more photographed image areas, so that the photographed image areas are developed under an optimum condition to have appropriate densities. In the first step, a region of the film, other than the photographed image areas, is exposed with a constant quantity of light. The region exposed to the constant quantity of light is then developed prior to the development of the photographed image areas. The density of the image in the region exposed to the constant quantity of light is detected and compared with a characteristic curve showing the change in density of the developed image in terms of the quantity of exposure light to find the optimum condition for development. The photographed image areas are then developed under the thus found optimum condition. The condition for development may be controlled by varying the film feed rate, the concentration of the developing reagent in the developing liquid, the quantity of the developing liquid supplied to contact with the film or by changing the temperature of the developing liquid. An additional region exposed to the constant quantity of light may be provided and used for setting the optimum condition for printing.
