The gelatin silver print is the most commonly used chemical process in black-and-white photography, and is the fundamental chemical process for modern analog color photography. As such, films and printing papers available for analog photography rarely rely on any other chemical process to record an image.
Gelatin silver process: This is the most traditional black-and-white emulsive process, introduced in the late 1800s and still available today. The image is developed through a wet process, using paper coated with a layer of silver salts and gelatin.
A self-portrait in mordançage style. Mordançage is an alternative photographic process that alters silver gelatin prints to give them a degraded effect. The mordançage solution works in two ways: it chemically bleaches the print so that it can be redeveloped, and it lifts the black areas of the emulsion away from the paper, giving the appearance of veils.
Initially Maddox tried other bases. He combined silver bromide with "vegetable gummy matters" (lichen, linseed, quince), and "starchy substances" (rice, tapioca, sago). "Often I fancied I was just within the doorway when the door closed, and other plans had to be tried." [2] Finally he tried gelatin from a packet of Nelson's Gelatine Granuals.

In analog photography, it is a chemical process carried out on metal salt-based prints, such as silver prints, iron-based prints (cyanotype or Van Dyke brown), or platinum or palladium prints. This darkroom process cannot be performed with a color photograph. The effects of this process can be emulated with software in digital photography.

Currently, the standard analog photographic printing process for black-and-white photographs is the gelatin silver process. [1] Standard digital processes include the pigment print, and digital laser exposures on traditional color photographic paper. [citation needed] Alternative processes often overlap with historical, or non-silver processes.
