Abstract: A photographic processor formed by an outer chamber with an inner chamber supported therein having walls which are spaced from the walls of the outer chamber. A cap seals both the inner and outer chambers and contains an opening through which liquid may be introduced into the inner chamber when the processor is upright. Openings are provided in the inner chamber adjacent the cap so that processing liquid may flow therethrough into the outer chamber when the processor is held horizontally and a liquid may subsequently flow therethrough and out through the opening in the cap when the processor is inverted.

Abstract: Light-monitoring apparatus is disclosed for use with a color printing process in which the mean printing conditions are determined and applied to all prints. Three photoelectric transducers responsive to the primary colors are arranged to receive light from the source, after filtering, with such light being screened from the photosensitive material on which the prints are formed. The exposure times for the process are then determined by the average intensity of the light impinging upon the photocells. The photocells may also be partially responsive to light passing through the negative or transparency to correct partially for density and/or color changes from transparency to transparency.
