ABSTRACT:
A method for preparing a silver halide emulsion is disclosed, comprising introducing a silver salt solution and a halide solution through separate introduction tubes, mixing the silver salt and halide solutions to react a silver salt and a halide to form silver halide grains and discharging a reaction mixture solution through a discharge tube by the use of a mixing apparatus in which the introduction tubes and the discharge conduit are linked together so that all center axes of the introduction and discharge tubes intersect at a single point, wherein the silver salt solution and the halide solution are independently introduced at a linear velocity of not less than 4.0 m/sec and a Reynolds number of not less than 3,000.
