Carbon Prints

Photographic prints using this process were made from the late 1860s to the 1940s. The name comes from the fact that carbon black was one of the first pigments used in this process, but many different colours are possible. The paper may be thick or thin, with a glossy or matte surface. Carbon prints have a subtle but distinctive “relief” appearance, when viewed under magnification, that makes the dark and light areas of the image seem to be of differing thickness.
