The tintype was introduced in 1853 by Adolphe Alexandre Martin. It was an immensely popular photographic medium, producing beautiful results in just minutes–the precursor to the modern Polaroid, but permanent.
While not actually produced on tin (modern tintypes are commonly on aluminum sheets), the collodion process was also used on glass, and called an Ambrotype.
Collodion tintypes (also called ferrotypes) are a challenge to produce. They require toxic, explosive chemicals; a deft hand; and a great deal of experimentation. The payoff, however, is huge: a unique, grainless image with an archival life nearly unequaled by paper-based prints.
A modern version of the historic tintype is also possible. Instead of collodion, a silver-gelatin emulsion is spread over the metal plate, and exposed. I have worked in both media.
All pieces are unique. Prices for tintypes are $350 for a 4×5 and $900 for an 8×10 plate. Archival prints of these plates are $300 for an 11×14, and metal print reproductions are available at 8×10: for $600. Please contact me about particular images you are interested in.
