Abstract
A silver halide photographic emulsion contains tabular grains each having a silver iodide content of 5 to 20 mol %, and having an aspect ratio of 2 or more in an amount of 50% or more of a total projected area of all grains, wherein the relative standard deviation of the distribution of the silver iodide content between the grains, is 8% or less. A multiple color photographic light-sensitive material contains the above emulsion in its highest-speed blue-sensitive layer. The method of preparing the emulsion includes a step of growing a silver iodide containing-area having a silver iodide content of 6 to 30 mol % in an amount of 50% or more of all silver amount under a condition of pBr of 0 to 3.0 by means of double jet method using an aqueous silver salt solution containing 1.0 to 10.0 mol/l of silver salt and an aqueous halide solution containing 0.01 to 0.1 mol/l of iodide.
