Photographic plate in chemistry

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. Early plates used the wet See more Astronomy Many famous astronomical surveys were taken using photographic plates, including the first Palomar Observatory Sky Survey (POSS) … See more The earliest flexible films of the late 1880s were sold for amateur use in medium-format cameras. The plastic was not of very high optical quality and tended to curl and otherwise not provide as desirably flat a support surface as a sheet of glass. Initially, a … See more • Camera • Film base • Photographic film See more The sensitivity of certain types of photographic plates to ionizing radiation (usually X-rays) is also useful in medical imaging and material science applications, although they have … See more Several institutions have established archives to preserve photographic plates and prevent their valuable historical information from being lost.
