ABSTRACT:
A method is provided for replenishing a Photographic developer solution in a processing apparatus which includes a developer tank, a developer-addition reservoir, and a replenishment station. The method is characterized in that developer-addition solution sufficient for an extended Period of time is contained in the developer-addition reservoir and fed to the developer tank at a rate higher than the standard replenishment rate for the process being operated, while the overflow from the developer tank is fed to the replenishment station where, at the end of said extended period, it is replenished to account for chemical consumption for the whole extended period and then returned to the reservoir.
