Formulary's Van Dyke Brown Printing Kit, as the name implies, produces beautiful brown images. It is similar to the Kallitype process but uses Ferric Ammonium Citrate as the sensitizer. This modification results in a print that needs no special developer, just a short water rinse and fixing. Van Dyke Brown printing does not have flexibility in contrast control nor the ability to change print color with development. However, the prints may be toned with printing-out-paper toners. This kit will produce 100 4x5" prints.

When I learned the Van Dyke Brown process and wished to experiment with it, I was astonished to discover that the ingredients were hard to get. I was delighted when I stumbled on this site, and could order a kit. The response from PF was great and the product is very good. I especially appreciate the clear and helpful instructions for both preparation and for using the VDB.
