Abstract
A photographic material is processed with a processing liquid by establishing a surface contact between the uppermost layer of the material and a flat porous spreading element impregnated with a low viscosity processing liquid. The impregnation is brought about by providing during or prior to processing for a contact between the spreading element in at least parts thereof with the liquid content of a container for the processing liquid. The spreading element may be flexible or rigid and may consist of woven or knitted fabrics, non-woven webs of endless filaments or staple fibres, non-woven webs of paper fibres, porous plastic foils or porous metal layers.
