ABSTRACT:
A photographic developing tray is described having such configuration as to provide, when placed at an angular position, a trough adapted to contain a certain amount of processing solution. The inner wall of the trough, so formed, has a predetermined slope whereby, upon gradually moving the tray into a horizontal position, the solution contained in the trough cascades over the sloping surface onto a photographic sheet material placed on the bottom of the tray at a substantially uniform flow pattern.
