Afghan War via Tintype
Tintype pictures (also melainotype and ferrotype) was an old photography technique popular in the 19th century. It took a direct positive on a sheet of iron metal that is blackened by painting, lacquering or enamelling. These were the Polaroid pictures of the Civil War, and could go from posing to picture in your hand in just a few minutes.
