Beatrice-1866 by Julia Margaret Cameron. The albumen print was invented in 1850 and was the most common type of print for the next 40 years. An albumen print was made by coating paper with a layer of egg white and salt to create a smooth surface. The paper was then coated with a layer of silver nitrate. The salt and silver nitrate combined to form light sensitive silver salts. This double coated paper could then be placed in contact with a negative and exposed to the sun to produce a print.
