Tintypes were an early form of photographs made by creating a positive on a thin sheet of metal coated in enamel. Despite the name, there isn’t any tin in tintypes. They replaced other types of vintage photography like daguerreotypes because they were cheaper and easier to make. After a few decades, tintypes would also be replaced with albumen prints that produced a higher quality image. Tintypes enjoyed the height of their popularity during the 1860s and 1870s which means they were predominantly used to cover the Civil War and the American Wild West.
