"A photographic paper used for printing out black and white prints; developed in the 1880s, used through the 1960s when color processes became popular. The paper contains a gelatin emulsion with a silver bromide salt. The sensitivity of the paper allowed the photographers to make contact prints and enlargements with artificial light. The prints may fade, yellow, or develop a dark iridescent appearance with age."@en . "silver gelatin papers"@en . . "silver gelatin paper"@en . . . "300417482" . "2018-03-06T13:49:26"^^ .
