Abstract:
A silver halide emulsion comprising silver halide grains, wherein the variation coefficient of equivalent-circle diameters of all the silver halide grains is 40% or less, and 70% or more of the total projected area of all the grains is accounted for by silver halide grains each satisfying the following requirements (i), (ii) and (iii):(i) a silver iodobromide or silver iodochlorobromide tabular grain having (111) planes as main planes thereof, (ii) a thickness thereof is 0.1 &mgr;m or less, and (iii) surface iodide contents in the main plane thereof meeting the following relations: Io<30 mol % and 0.7Iowherein â€œIsâ€  is an average value of surface iodide contents (Ip's) in the main plane of each grain and â€œIoâ€  is an average value of the â€œIsâ€  values of all the tabular grains.
