Term - Lippman process
|Lippman process||SWPP Photographic Glossary|
Wednesday 28th September 2016
An early colour process invented by Professor Gabriel Lippmann (1845 1921). Light first passed through an almost transparent emulsion layer and was then reflected back by a layer of mercury. The interference between reflected and incident light produced a latent image in the emulsion which could be given b&w processing, but when backed with a mirror appeared in colour.
