For versatility, nothing equals liquid photographic emulsion. It allows you to print on materials of any size and shape, including wood, paper, metal, glass, ceramic, plastic, or anything from a wall to a walnut (see gallery). Just brush on the emulsion then expose and process with standard black&white developer.
Liquid Light all-purpose emulsion, Liquid Light VC variable-contrast emulsion and Ag-Plus high-sensitivity emulsion have been the world’s standard for 30 years.
