An albumen print is a photograph printed on paper that is coated with an emulsion of egg white and brushed with light-sensitive silver salts. It is usually brown or sepia in color, with a shiny surface. Albumen prints became popular in the early 1860s, and remained the most common form of photograph until the turn of the century.
