Lumière Alticolor
Description
“Lumière Alticolor (1952–1955): rolls and pack films on celluloid base. Alticolor starch grains are smaller but of less regular shape than those used in Filmcolor (Fig. 2.74). There are no black pigment particles; therefore, Alticolor transparencies are more transparent than the other Lumière films. Under polarizing light, the potato starch grains will show a typical spherical cross in the center. The lack of pigment filler in between the colored starch grains is visible only at high magnification (200× or higher).”
