In … WebPhotographic plates face significant structural and chemical challenges unique to their make-up. There are two types of photographic glass plates; collodion wet plates and gelatin dry plates. Structurally, collodion wet plates are held together with a specific type of emulsion , made using a silver halide mixture in gelatin.
Photographic plates preceded photographic film as a capture medium in photography, and were still used in some communities up until the late 20th century. The light-sensitive emulsion of silver salts was coated on a glass plate, typically thinner than common window glass. See more Glass plates were far superior to film for research-quality imaging because they were stable and less likely to bend or distort, especially in large-format frames for wide-field imaging.
