Old-style photo is a term used to describe a type of photograph that was popular in the 19th century. The most common type of old-style photo is the tintype, which is a 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 a photographic print. The tintype process was invented in the mid-19th century and remained popular until the early 20th century.
