The term photogelatin process refers to a method of printing photographs on gelatin-coated paper. Alternative names for this process include gelatin silver process, photographic process, and gelatin emulsion process. The term is derived from the combination of "photo," meaning light, and "gelatin," the material used to coat the paper. Other synonyms for this process include photographic emulsions, silver halide process, and gelatin bromide process. This process rose to popularity during the 20th century but has now been largely replaced by digital photography. However, there are still enthusiasts who prefer the tactile experience and unique qualities of the photogelatin process.
