- History / Biographical
- Dufay Historical Significance: Dufaycolor is an additive colour photographic film process invented by Louis Dufay and introduced for still photography in 1935. Popular with amateurs and professional photographers, it was used for photojournalism and advertising purposes. Dufaycolor was used only into the 1950s when it was superseded by superior colour processes like Technicolour and Kodachrome. Dufaycolor transparencies are viewed either by projection or transmitted light. The photographer could use Dufaycolor roll film (35mm) or ‘flat film’ in preloaded ‘film packs’ for larger sizes. Dufaycolor transparencies are often mounted in a Dufaycolor slide mount, a black paper mount embossed with “Dufaycolor” on the top right hand corner. Riggall’s use of Dufaycolor is significant because of the limited commercial production (1935 - 1950), the economic implications of using Dufaycolor (Dufaycolor film could be nearly three times the price of other commercially available film stock), and Riggall’s own limited use of this format (ca. 1939 to 1941). The 486 Dufaycolor transparencies contained within the Bert Riggall fonds are important records of early color photography and Riggall’s experimentation with the process. Riggall ordered his Dufaycolor supplies from “Dufaycolor Service” and the W.E. Booth Company Limited in Toronto. Also in the Bert Riggall fonds, is “The Dufaycolor Book” published by Dufay-Chromex Limited found at: M376 / 126, 127
