The most popular black and white process of the 20th century was gelatin silver, in which the image consists of silver metal particles suspended in a gelatin layer. Gelatin silver papers are commercially manufactured by applying an emulsion of light-sensitive silver salts in gelatin to a sheet of paper coated with a layer of baryta, a white pigment mixed with gelatin. The sensitized paper, generally fiber-based, is exposed to light through a negative and then made visible in a chemical reducing solution. William Henry Fox Talbot introduced the basic chemical process in 1839, but the more complex gelatin silver process did not become the most common method of black-and-white darkroom photography until the late 1910s. Because the silver image is suspended in a gelatin emulsion that rests on a pigment-coated paper, gelatin silver can be sharply defined and highly detailed in comparison to platinum or palladium, in which the image is absorbed directly into the fibers of the paper.
