Abstract:
A silver halide emulsion comprising silver halide grains, wherein at least 50% of total grain projected area is accounted for by silver halide regular crystal grains exhibiting a proportion of a (100) face per grain of 70% to 95% and having an average iodide content of not more than 5 mol %; said silver halide grains having an internal high iodide phase having an average iodide content of not less than 7 mol % and accounting for 0.1 to 15% of the grain volume and an outermost surface layer having an iodide content of not more than 10 mol %; said high iodide phase being in the region at a depth of from 7 to 27% from the (100) face, based on the distance between the center of a grain and the (100) face.
