Photographic Glass Plates

Case : 558

Photographic plates preceded photographic film as a capture medium in photography. Early plates used the wet collodion process. Before the film era and way before the digital era, photographic emulsions were made on glass supports, known as glass plate negatives. The wet plate process was replaced late in the 19th century by gelatin dry plates. Glass plate photographic material largely faded from the consumer market in the early years of the 20th century, as more convenient and less fragile films were increasingly adopted.  Two types of glass plate negatives exist: the collodion wet plate invented by Frederick Scoff Archer, in use from the 1850s, and the silver gelatin dry plate created by Dr. Richard L. Maddox, in use from the 1870s. Dry plate glass negatives were in common use between the 1880s and the late 1920s. Many museum and library in Europe  (especially in France and Italy) used this glass plate negatives to conserve the collection during 1850-1890, after that, replaced them by new technic on negative paper. Many historic tarot decks and printing documents that has been captured for the stockade and transfer and now they become the first photographs of tarot in the world.
