Gelatin A collagen-based substance made from animal by-products. It is best known in its gelatinous form, but actually beings as a brittle, translucent sheet or flakes.
In photography, gelatin can be used in the gelatin silver process. This process involves silver particles mixed with gelatin, which then coat a surface such as glass or paper, used to record the image. The photographic material will be stable for many years with this coating, and the images can be developed after long periods of time. |
