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.
Claims7
A method of processing photographic material comprising the steps of:
- developing the material in a developing solution;
- bleaching and/or fixing the material;
- and
- washing the material,
- characterized in that the material is tempered in a conditioning chamber prior to entering the developing step such that the temperature of the material is adjusted to the temperature of said developing solution and passed onto the developer solution while the material is still at the correct temperature for development.
