A silver halide photographic light sensitive material IS DISCLOSED, comprising a support having thereon a yellow dye image forming layer, a magenta dye image forming layer and a cyan dye image forming layer, wherein when the photographic material is subjected to exposure of not more than 10 sec. per pixel element and further to color developing to form yellow, magenta and cyan images, a variation at multiple exposure, based on non-multiple exposure, of an average gradation, which is a slope that connects two pints corresponding to densities of 0.5 and 1.5 on a characteristic curve of each of the yellow, magenta and cyan images, is not more than 10%.

Disclosed is a method of producing a silver halide photographic emulsion comprising steps of:

Method of producing a silver halide photographic emulsion

A desalting method of a silver halide emulsion is disclosed, comprising removing soluble salts from the silver halide emulsion by electrodialysis, wherein said electrodialysis is carried out at a pH within a range of .+-.0.5 of an isoelectric point of a gelatin contained in the silver halide emulsion. Furthermore, by adding a salt during the course of the electrodialysis, the concentration of the emulsion is accomplished concurrently with desalting thereof.
