Gelatin Silver Print
Gelatin silver prints are made on paper that has been coated with gelatin containing light-sensitive silver salts and then exposed to light, usually through a negative. Some gelatin silver papers were used for creating images solely through exposure to light while others required chemical development after exposure to produce the final image. The latter, introduced in the 1880s, became the dominant black-and-white photographic process of the twentieth century and continues in use today. Numerous gelatin silver papers became commercially available, resulting in images with varying tones, surface texture, and gloss.
