Silver halide emulsion and method of preparing the same

A method of preparing a silver halide photographic emulsion comprising silver halide grains which each have a host tabular grain part and a part grown on the outside thereof, wherein in said host tabular grains parts, at least 50% of total projected area of the silver halide grains are accounted for by silver halide tabular grains having {111} main surfaces, and said silver halide grains comprises the main surface of the host tabular grain part subjected to junction on the main surfaces with high-iodide epitaxial phases comprising silver halide containing at least 97 mole % of silver iodide and the lateral face of the host tabular grain part comprises silver halide having an iodide content of substantially 5 mole % or below;

• and
• wherein said high-iodide epitaxial phases are formed under the following conditions (1) and/or (2) and then silver halide phases with low silver iodide contents are disposed on the lateral face of the tabular grains:
• (1) pAg is maintained to less than 6.4, and
• (2) a compound having (100) face selectivity is present.
