Descripción
A process to make photographic prints using a colloid emulsion of bichromated gum arabic as the binder and pigment as the final image material. The image is formed as the emulsion hardens in relation to exposure and is developed by washing away the unhardened emulsion to reveal the support, forming the highlights and midtones.
