Chemical treatment then reduced the crystals to microscopic particles of metallic silver in proportion to the intensity and duration of their exposure to light, resulting in a visible image.The later and more convenient dry process was similar but used a gelatin emulsion which could be applied to the plate long before use and exposed in the camera dry.One or more hardy, lightweight, thin tintypes could be carried conveniently in a jacket pocket.They became very popular in the United States during the American Civil War.

It was first called melainotype, then ferrotype by a rival manufacturer of the iron plates used, then finally tintype.Tintype portraits were at first usually made in a formal photographic studio, like daguerreotypes and other early types of photographs, but later they were most commonly made by photographers working in booths or the open air at fairs and carnivals, as well as by itinerant sidewalk photographers.Because the lacquered iron support (there is no actual tin used) was resilient and did not need drying, a tintype could be developed and fixed and handed to the customer only a few minutes after the picture had been taken.In both processes, a very underexposed negative image was produced in the emulsion.

Its densest areas, corresponding to the lightest parts of the subject, appeared gray by reflected light.There are two historic tintype processes: wet and dry.In the wet process, a collodion emulsion containing suspended silver halide crystals had to be formed on the plate just before it was exposed in the camera while still wet.The tintype saw the Civil War come and go, documenting the individual soldier and horrific battle scenes.
