Webdry plate, in photography, glass plate coated with a gelatin emulsion of silver bromide. It can be stored until exposure, and after exposure it can be brought back to a darkroom for development at leisure.

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 See more The earliest flexible films of the late 1880s were sold for amateur use in medium-format cameras.
