In Chap. 2 we described emulsion layers, which contain silver halide grains and oil droplets in gelatin. The silver halide grains capture light, i.e., they record the arrival of photons that enter the shutter when a photograph is taken. The oil droplets contain dye couplers which, during the development of the film, produce colored dye. Emulsion layers also contain other ingredients. Whereas the silver halide grains and oil droplets occupy a substantial volume of the emulsion, the other materials occupy a negligible volume.
