 Prizma began in 1916 as an additive system similar to Kinemacolor.However, after 1917, Kelley reinvented the process as a subtractive one with several years of short films and travelogues, such as "Everywhere With Prizma" (1919) and "A Prizma Color Visit to Catalina" (1919) before releasing features such as the documentary "Bali the Unknown" (1921), "The Glorious Adventure" (1922), and "Venus of the South Seas" (1924).A Prizma promotional short filmed for Del Monte Foods titled "Sunshine Gatherers" (1921) is available on DVD in Treasures 5 The West 1898–1938 by the National Film Preservation Foundation.
