Uvachrome was an early 3 color subtractive color process for still photography invented by German-born chemist Dr. Arthur Traube (1878-1948) and commercialized from 1922 to 1931 by Uvachrom Aktiengesellschaft, competing with the Lumiere Autochrome color process. The Uvachrome and Uvatype images on glass plates are a variation of the dye imbibition process. The original glass plates and Dr. Traube’s correspondence, patents and other materials are in the collection of the Eastman Museum. These rare chromes are now very faded and yellowed, requiring extreme color correction to yield a full color image.
