A method for preparing a silver iodobromide emulsion comprising silver iodobromide grains containing an average silver iodide content of 2 mol % or less is provided, wherein the silver iodobromide emulsion is prepared by incorporating simultaneously a silver salt solution and a solution of bromide and iodide salts into a hydrophilic colloid solution containing silver halide seed grains to grow the silver iodobromide grains from the seed grains, wherein the total volume of the solutions of the silver salt and the bromide and iodide salts is within a range of 2 to 10 times the volume of the hydrophilic colloid solution containing the seed grains in an amount of 0.5 to 5.0% by volume.
