Heather, Although many Civil War soldiers had their pictures taken (they called them "likenesses" at that time), there was no official or systematic process by which this was done by the governments or armies involved. All photos taken were at the initiative and expense of the individual photographed. Ferrotypes (usually called "tintypes") were fairly expensive, one-of-a-kind images costing as much as $5, a substantial expense for the time. The glass plate negative / albumen print process yielded substantially cheaper photos, but many photographers did not have access to the print paper which came from France, particularly Southern photographers whose paper supply was impeded by the blockade.
