Abstract

A method for processing photographic silver halide materials with aqueous processing baths which are replenished during processing, in which at least one chemical substance in the form of a plurality of solid bodies of geometrically defined shape and of the same size and composition is added to replenish at least one processing bath, is distinguished by a low consumption of chemicals and by a minimal accumulation of overflow for subsequent disposal.
