Abstract
It is important to control the temperature during the development stage of a photographic process in order to maximize the efficiency thereof. This is a particular problem when photographic materials are processed in high throughput processors which operate with reduced volume chemistry as these material have a tendency to cool the developer solution if not at the correct temperature. Described herein is a method for improving the temperature stability of the material to be processed by heating it before processing. The material is passed through a conditioning chamber where it is heated to the desired processing temperature prior to entering the development stage of a processor.
