ABSTRACT:
A method for producing a silver halide photographic emulsion, a method for producing thereof, and a light-sensitive material using the same, the method comprising the steps of: (a) producing a host emulsion comprising silver bromide or silver iodobromide tabular grains having an average silver iodide content (I.sub.1 mol %) of the entire silver halide grains of 5 mol % or less, in which 60% or more of the projected area of the entire silver halide grains accounting for tabular grains having an aspect ratio of 3.0 or more; (b) dissolving a periphery of the tabular grains completely with an iodide ion being added to the host emulsion; and then (c) producing final tabular grains by reclaiming a periphery containing silver iodobromide from the region containing the periphery having been completely dissolved.
