Method for processing photographic sheet material
A method of processing photographic sheet material comprises passing the sheet material along a sheet material path (20) through a processing apparatus comprising a plurality of processing cells (12, 12', 12"), and causing processing liquid to pass across the surface of the sheet in at least one of the cells. The cell is a closed cell the speed of liquid flow across the sheet material, as measured in a direction perpendicular to the direction of the sheet material path (20), is at least 3 times the speed of the sheet material along the sheet material path (20) and the resultant liquid flow speed is at least 100 mm/sec. The consistency of reaction kinetics at the sheet material surface are improved.
