Abstract

In known photographic processing apparatus, quality of the photographs produced can be adversely affected by drift in the paper processor of the apparatus. One cause of drift is incorrect replenishment of the chemicals used in the paper processor. In processing apparatus which utilise only small volumes of chemicals, drift can be caused by replenishment rates not matching the dye formed on the prints being processed, and an operator would need to take steps to adjust the processor. Described herein is an improved method of controlling the replenishment rate of chemicals in photographic processing apparatus. The method comprises deriving a control signal from the image to be exposed on to photographic material and using the derived signal to control the replenishment rate of the chemicals.
