Description

Original selenium toned Gelatin Silver photograph by Julia Brett Christopher, "Lava Tube, California." Individually handmade by Christopher from 6x7 format Kodak Tri-X film with fiber-based Bergger Warmtone paper. Mounted on cotton rag museum board. Signed in pencil on mount with title, date and numbered in a limited edition of 50 on mount verso. The edition is cumulative, not per size. While the artist will not make more than 50 originals from the negative during her lifetime, it is important to note that each original she makes is unique and visibly different from the others in the edition.

The most popular black and white process of the 20th century was gelatin silver, in which the image consists of silver metal particles suspended in a gelatin layer. Gelatin silver papers are commercially manufactured by applying an emulsion of light-sensitive silver salts in gelatin to a sheet of paper coated with a layer of baryta, a white pigment mixed with gelatin. The sensitized paper, generally fiber-based, is exposed to light through a negative and then made visible in a chemical reducing solution. William Henry Fox Talbot introduced the basic chemical process in 1839, but the more complex gelatin silver process did not become the most common method of black-and-white darkroom photography until the late 1910s. Because the silver image is suspended in a gelatin emulsion that rests on a pigment-coated paper, gelatin silver can be sharply defined and highly detailed in comparison to platinum or palladium, in which the image is absorbed directly into the fibers of the paper.
