One notable achievement, however, is that it appears the use of albumen allowed an early form of dry-plate photography. 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.
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.
