ABSTRACT:
A light-sensitive silver halide photographic emulsion is disclosed, wherein at least 70% of the total projected area of silver halide grains are tabular grains having an average aspect ratio of a diameter to a thickness of 2 or more, an average value of the longest distances between two or more parallel twin planes contained in the respective tabular grains is 0.008 .mu.m or more, and a variation coefficient of the longest distances between parallel twin planes is 35% or less, and wherein the silver halide emulsion is spectrally sensitized with a substantially slightly water-soluble sensitizing dye by adding the dye to the emulsion in the form of a dispersion of solid particles dispersed in an aqueous solution substantially free from an organic solvent or surfactant.
