Van Dyke Brown
Seen in this video are several prints available through my Etsy store which can be found at the top of this page at http://handmadeonpeconicbay.com
Van Dyke Brown is an early photographic printing process.
The Vandyke brown print is based on the first iron-silver process, the argentotype, invented in 1842 by the English astronomer, Sir John Herschel. Both processes utilize the action of light on ferric salts and their chemistry is very similar. The Vandyke process gets its name from its similarity in color to the deep brown pigment used by the Flemish painter Van Dyck. Vandyke brown prints are very simple and economical to make, with the sensitizers consisting of three readily available chemicals. Clearing is carried out in water and fixing is done in a weak solution of hypo.
