Method of preparing a silver halide photographic emulsion

A method for preparing a silver haloiodide emulsion, which method comprises the steps of

• (i) preparing a silver halide host emulsion in a reactor vessel, and
• (ii) simultaneously adding jets of soluble silver salt and iodide salt solutions to the reactor vessel to precipitate silver iodide onto the silver halide host emulsion, the jets being added in at least two pulses separated by a pause, where respective flow rates of the silver salt and the iodide salt solutions added are at least V/Vo×100 ml/minute each during the pulses, wherein Vo is 18 l and V is the total volume of emulsion precipitated in the reactor vessel.
