Platinum Style Photography Tunnel 2014- 0719

Platinum prints, also called platinotypes, are photographic prints made by a monochrome printing process that provides the greatest tonal range^{[clarification needed]} of any printing method using chemical development.^{[citation needed]}

Platinum prints are made by photographers and favored by collectors because of their tonal range, the surface quality and their permanence. A platinum print provides a broad scale of tones from black to white. The platinum tones range from warm black, to reddish brown, to expanded mid-tone grays^{[clarification needed]} that are unobtainable in silver prints.^{[1][dubious – discuss]}

Unlike the silver print process, platinum lies on the paper surface, while silver lies in a gelatin or albumen emulsion that coats the paper. As a result, since no gelatin emulsion is used, the final platinum image is absolutely matte with a deposit of platinum (and/or palladium, its sister element which is also used in most platinum photographs) absorbed slightly into the paper.^[2]

Platinum prints are the most durable of all photographic processes^{[dubious – discuss]}. The platinum group metals are very stable against chemical reactions that might degrade the print—even more stable than gold. It is estimated that a platinum image, properly made, can last thousands of years.
