A method for producing a photographic emulsion is disclosed. The method includes the process of adding a dispersion of a substantially water-insoluble photographic additive to a photographic emulsion. The dispersion being prepared merely by mechanically grinding and dispersing the photographic additive in a form of fine grain having a size of 1.mu. or less in an aqueous system adjusted to a pH value of 6 to 8 and controlled to a temperature of 60.degree. to 80.degree. C. The additive is included in the photographic emulsion without the need of an organic solvent. The emulsion of the invention can be easily and quickly coated to form a uniform layer.
