The daguerreotype is the only photographic process that used a thin coating of highly
polished silver on a copper support. The surface of the daguerreotype was
very fragile and that is the reason why glass was used on top of the plate. A tintype
is a photograph made on a sheet of iron instead of a piece of paper Most
tintypes were brownish in color and the most common size was about 2 ½ " x 3 ½".
