black-and-white photograph

n. A photographic image in which all colors are reproduced in varying shades of a neutral tone, especially one made using a gelatin silver process. A monochromatic photographic image.


The vast majority of modern, monochromatic photographs are made using the gelatin silver process. These photographs usually have a very neutral tone. Other processes, especially 19th-century processes, used to make monochromatic images include albumen, collodion, platinum, and palladium, which may have a pronounced warm tone, or cyanotypes, which have a pronounced blue tone. 'Black and white' is sometimes used to when 'monochromatic' is the more accurate term.
