ABSTRACT:
Apparatus for controlling the concentration of silver ions during the precipitation of a silver halide emulsion in a precipitation vessel. A pair of valve assemblies control the introduction respectively of a silver salt and a halide salt into the precipitation vessel, each in accordance with a preselected program. The actual silver ion concentration in the vessel is measured, linearized and the preselected program for the silver salt introduction modified in accordance with a desired or programmed silver ion concentration.
