Peter
Mawdsley invented the first photographic paper with
a gelatin emulsion. Gelatin was used as an emulsion
to bind light sensitive silver salts to a paper or
other support. The gelatin print is made by exposing
the paper to a negative. The paper is then immersed
into chemicals to allow the latent image to emerge.
Albumen prints were replaced by gelatin emulsion
developing-out paper by the late 1890s. Gelatin silver
(standard Black & White) prints have dominated
the market since the mid-1900s.
