Photographic print processing apparatus according to the present invention may comprise a rotatable drum into which may be introduced a quantity of photographic print processing fluid. A device is provided for controllably introducing the processing fluid into the drum and for controllably introducing water or other appropriate fluid for the washing of photographic printing papers at appropriate stages during the development process. The apparatus may be powered manually or may be provided with a motor drive mechanism to achieve selective rotation of the drum during processing. The drum may be rotated in one direction for processing and may be rotated in the opposite direction for expelling the processing fluid from the drum into a reservoir provided to contain the expelled fluid. Selective directional rotation of the drum may be achieved by the reversible electric motor that may be actuated by mercury switches positioned on an actuating lever which switches are selectively actuated to energize the motor depending upon relative positioning of the lever as the lever is actuated for control purposes.
