this is pretty amazing. i had no idea anyone was still making tintypes. here's a rundown on what a tintype is:
In 1856 Hamilton L. Smith of Ohio patented a new photographic method that came to be known as tintype. These one-of-a-kind images are made directly on a thin iron plate that has been coated with chemicals, exposed in a camera while still wet, and developed on the spot. Because the plates are iron, not tin, the more proper term is ferrotype, but the photographs have been commonly called tintypes from the beginning. The process, less expensive than daguerreotype and more durable than other earlier methods of photographic portraiture, became very popular during the Civil War and remained so into the 20th century until newer processes that could produce multiple images took over.
here's a site of tintypes which features portraits of cowboys/cowgirls which i found much more interesting than i expected to. it's also where the above quote came from. and here's another of work by a university student(where the picture above comes from). interesting that both sites are mainly of portraits. via toycamera.com.
