Finding a true to life glimpse of the past was not possible until the early 19th century, with the first inventions of primitive photographic methods. One that quickly became very popular in antebellum Charleston was the daguerrotype, which was essentially a method to produce a mirror-like image. Invented by Frenchman Louis Jacque Mande Daguerre in 1839, the creation of an image was a multi-step process of polishing sheets of silver-plated copper, injecting gas fumes that made the surface sensitive to light, then exposing it through an aperture to light. A person standing in front of the device would have their mirror image imbedded by then adding mercury vapor and a series of rinsing, drying and sealing to complete the process. By 1850, numerous daguerrotype studios had opened in Charleston, and the old adds are still very illuminating.
