Daguerreotype
Invented by Louis-Jacques-Mandé Daguerre and introduced worldwide in 1839, daguerreotype was almost completely superseded by 1860 with new, less expensive processes yielding more readily viewable images. In the late 20th century, there was a revival of daguerreotypy by a small number of photographers interested in making artistic use of early photographic processes.
Tintype
The tintype photograph saw more uses and captured a wider variety of settings and subjects than any other photographic type. It was introduced while the daguerreotype was still popular, though its primary competition would have been the ambrotype.
