Abstract

A process for the treatment of a photographic material with a bath containing at least one processing chemical, in which, after the treatment bath, the photographic material is guided upwards through a sloping compartment which closely surrounds the photographic material and is washed from above with water which, under the effect of gravity, flows in countercurrent to the photographic material, leads to a surprisingly marked reduction in the chemical load of the material.
