A photographic paper used for developing or printing out black and white prints; developed in the 1880s, and still used for this type of chemically-based printing process. The paper is coated with a gelatin emulsion containing a silver bromide salt. The sensitivity of the paper allows photographers to make contact prints and enlargements from positives or negatives with artificial light. The prints may fade, yellow, or develop a dark iridescent appearance with age if not properly processed.
