Happy Halloween to all. A fun App giving A 19th century Look.The “Tintype” enjoyed the longest success of any 19th century photographic process in history. Even though its popularity was overcome by new paper images in the 1860s, it was still produced until the early 1900s. In the latter years tintypes were mostly produced as souvenirs at carnivals and side shows.The tintype, actually misnamed, is an iron plate that has been coated with a black lacquer. This lacquer (sometimes referred to as japan, from the substance's country of origin) provided a smooth tonal surface on which to develop the image and it prevented the iron from rusting. The tintype was more commonly known in its time as a ferrotype (ferrous being the name of iron from your chemistry class), and melainotype, a variation of the melano prefix meaning dark or black.
