Abstract: In photographic processing apparatus, by-products are produced due to the chemical reactions which occur during the processing of photographic materials. It is known to remove some of these by-products in accordance with the area of photographic material processed and a knowledge of the average level of production of the by-products. This leads to inaccuracies in maintaining a fixed level of the by-products in the processing solutions. Described herein is a method of controlling a subsystem which removes by-products from the processing solutions by using data relating to the exposure given to a photographic material in the printing stage of the processing apparatus to calculate the amount of by-products produced so that they can be exactly removed from the processing solutions.

Abstract: A color image can be obtained from a color photographic element by multiple color development steps. The first color development is carried out in the usual manner after imagewise exposure. The second color development step is carried out after bleaching with a rehalogenating bleaching agent, and is used to develop only rehalogenated silver halide. This specific development is possible by either using a chloride rehalogenating agent in the bleaching solution, using a sulfite fixing agent before bleaching, or by fogging the element between bleaching and the second color development step.
