ABSTRACT:
A method for producing a silver halide emulsion, said method comprising: adding silver nitrate to a halogen compound to form an emulsion grain; and doping a non-labile selenium compound in an amount, in terms of selenium added, of from 1.0.times.10.sup.-8 to 1.0.times.10.sup.-6 mol per a unit surface area of 1 m.sup.2 of said emulsion grain, at the time when from 10 to 49% of the total silver amount used for the formation of said emulsion grain is added.
