An old-fashioned photograph is a type of photograph known as a tintype. Tintypes were popular in the 19th century and were made by creating a direct positive on a thin sheet of metal. The process involved coating a thin sheet of iron with a light-sensitive emulsion and then exposing it to light. The resulting image was then developed and fixed onto the metal plate. Tintypes were popular because they were relatively inexpensive and could be produced quickly.
