WebOct 1, 2024 · The photographic process. A photographic film, plate, or paper consists of a support (film, glass, or paper) to which a light-sensitive emulsion is applied. The emulsion … 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.

WebThomas Baker first experimented with making photographic dry plates in the early 1880s. He painstakingly recorded his emulsion recipes, and the results of his many chemistry experiments, in this formulae book, which he kept in use for almost 40 years.
WebSome significant instruments earlier in the century that used photographic plates to collect ions were called mass "spectrographs," as distinct from "spectrometers," while "mass spectroscope" and "mass spectroscopy" served as inclusive labels, but that distinction and terminology have become uncommon except in reference works.
