Photographers’ Formulary Van Dyke Brown Printing Kit
Formulary’s Van Dyke Brown Printing Kit produces brown images. It is similar to the Kallitype process but uses ferric ammonium citrate as the sensitizer. Prints do not need a special developer, just a short water rinse and fixing. Prints may be toned with printing-out-paper toners. This kit will produce 100 – 4×5″ prints.
