| | COLOR THEORY-AUTOCHROME |
 | | AUTOCHROME was a photographic transparency film patented in America, June 5,1906 (No.822,532) by Auguste and Louis Lumiére of Lyons, France (FR.Pat.No. 339,223, 1903). |
 | | Like other techniques of the time, it employed the additive method, recording a scene as separate fl and white images representing red, green and blue, and then reconstituting color with the help of filters. |
 | | The final photograph has a beautiful look with wide tonal gradation and if you could see an original well preserved Autochrome today, you would be amazed at the extrodinary way they age, and can in fact appear as though they were processed only yesterday. |
