Photographic Reproduction Processes

The manual presents practical, non-silver photographic reproduction methods based on iron, uranium, and other salts, combining theoretical explanation with detailed recipes. It surveys cyanotype, cyanofer, ferro-tannate (ink) processes, cuprotype, aniline and primuline (diazotype) techniques, uranotype, platino-type, carbon printing, tracing on metal and graphotypy, illustrating coating, exposure, development, fixing and mounting. Historical experiments and authority excerpts illuminate chemical mechanisms and sensitivities, while illustrations and an appendix collect variations, troubleshooting, and safety cautions for handling reactive compounds.
