ABSTRACT:
Black-and-white silver halide photographic materials are processed with the use of a processor which requires no silver recovery means, no water supply and no drain. The photographic material is transported through a series of processing tanks including a developer tank, one or more fixer tanks, and one or more wash or stabilizer tanks. Replenishment of the fixing solution is controlled so that the rate of replenishment of the fixer tank is a function of the level of one or more chemicals in the last tank through which the material is transported.
