Frederick Charles Luther Wratten (1840, England – 8 April 1926,Macmillan Biographical Encyclopedia of Photographic Artists & Innovators. By Turner Browne and Elaine Partnow. London: Collier Macmillan Publishers, . (MacBEP) London) was an English inventor. Wratten started his career as a school teacher and organist, and moved to London in 1861 to become a clerk at Joseph Solomon's Photographic & Optical Warehouse. His work at the warehouse stimulated his interest in photography, and while there he learned how to use gelatin in a sensitized emulsion and began experimenting on his own. In 1876, Wratten developed the use of alcohol in drying gelatin emulsion and removing unwanted silver nitrate. This process was described in the ''British Journal of Photography'' of 1877 and 1878. During the course of his experiments, Wratten formed a partnership with Henry Wainwright (1877~) for the manufacturing and sale of photographic supplies. ''Wratten & Wainwright'' were the first firm in ...

England
England is a country that is part of the United Kingdom. It shares land borders with Wales to its west and Scotland to its north. The Irish Sea lies northwest and the Celtic Sea to the southwest. It is separated from continental Europe by the North Sea to the east and the English Channel to the south.

Early life and education Mees was born in Wellingborough, England, the son of a Wesleyan minister. He attended the University of London. In 1906 he was awarded his D.Sc. with a dissertation on photographic theory.

Wratten Number
Wratten numbers are a labeling system for optical filters, usually for photographic use comprising a number sometimes followed by a letter. The number denotes the color of the filter, but is arbitrary and does not encode any information (the 80A–80D are blue, the next filters in numerical order, 81A–81EF, are orange); letters almost always increase with increasing strength (the exception being 2B, 2A, 2C, 2E). They are named for the founder of the first photography company, British inventor Frederick Wratten. Wratten and partner C.E.K. Mees sold their company to Eastman Kodak in 1912, and Kodak started manufacturing Wratten filters. They remain in production, and are sold under license through the Tiffen corporation. Wratten filters are much used in observational astronomy by amateur astronomers. Color filters for visual observing made by GSO, Baader, Lumicon, or other companies are actually Wratten filters mounted in standard or 2 in (nominal, 48 mm actual) ...
