Photographic emulsion 2026-10-18
A photographic emulsion is a coating that responds to light to record an image in photography, for example on a photographic plate. Silver halide crystals, commonly silver bromide, are dispersed in gelatin. Exposure leaves a latent image. A developer produces dark silver grains and fixing removes remaining sensitive material. A microscope can reveal a charged particle's path through the coating: the basis of nuclear emulsion particle detection.[ref]
