Claims
- 1. A method for processing an exposed silver halide photographic material comprising the steps of:(a) developing of said photographic material in a developing solution containing a silver halide developing agent of the ascorbic acid type; (b) continuously measuring the concentration of said developing agent of the ascorbic type by ultraviolet spectrophotometry at a wavelength preselected depending on the particular developing agent of the ascorbic type in the range of from 200 to 400 nm; and (c) at a predetermined value of the spectrophotometry measurement, generating a signal that actuates the replenishing of said developing solution.
- 2. The method of claim 1, wherein the spectrophotometry measurement monitors the deviation of the concentration of the developing agent of the ascorbic acid type from a preset value.
- 3. The method of claim 1 wherein said developing solution contains a second developing agent that does not interfere with the spectrophotometry measurement of said first developing agent of the ascorbic acid type.
