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.
Photographic processing transforms the latent image into a visible image, makes this permanent and renders it insensitive to light. [1] All processes based upon the gelatin silver process are similar, regardless of the film or paper's manufacturer.
The process rapidly spread and became a dominant method in Europe and America by 1894 since it had a visibly different color tone compared to albumen and gelatin silver prints. Late 1880s: Gelatin silver print This has been the major photograph printing process since the late 1880s up to the present. [3] Prints consist of paper coated with an ...
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.
A single overall colour underlies the image and is most apparent in the highlights and mid-tones. From the 1870s albumen printing papers were available in pale pink or blue, and from the 1890s gelatine-silver printing-out papers in pale mauve or pink were available. There were other kinds of tinted papers as well.

Photographic emulsion is a light-sensitive colloid used in film-based photography. Most commonly, in silver-gelatin photography, it consists of silver halide crystals dispersed in gelatin. The emulsion is usually coated onto a substrate of glass, films (of cellulose nitrate, cellulose acetate or polyester), paper, or fabric.
