An antique photograph is a type of photograph that was produced in the 19th and early 20th centuries. The term 'antique photograph' can refer to a variety of different types of photographs, including tintypes. Tintypes are a type of photograph made by creating a direct positive on a thin sheet of metal coated with a dark lacquer or enamel and used as a substitute for the photographic print. They were popular from the 1860s to the early 20th century and were often used for portraiture.
