摘要
The invention is generally accomplished by a method of forming a silver halide emulsion in which digestion of nucleated silver halide grains is carried out in a halide solvent concentration of between about 0.0015 and about 0.015 normal. In a preferred embodiment the solvent utilized is ammonium hydroxide and grains of a thickness of between about 0.05 and 0.5 micron having an equivalent circular diameter of about 0.05 to about 2.0 microns are produced. It is also preferred that the grains be nucleated in a bromide solution having a bromide ion concentration of between 0.0075 and about 0.6 normal. IMAGE
