ABSTRACT:
A photographic processing drum includes a trough coaxially arranged within and spaced apart from the interior surface of the drum. A cap sealingly fitted to one end of the drum includes separate channels, isolated from each other, for conducting fluids into and out of the drum. Fluids introduced into the inlet channel are emptied directly into the trough without first contacting the interior surface of the drum. A method for employing the photographic drum in the processing of light-sensitive emulsions is also discussed.
