Appendix D: 3 Strip Color:

Color system in which three color-separation negatives were produced on black-and-white film. 3 Strip color is often used synonymously with the trade mark, Technicolor. In the Technicolor three-component system, light reflected from the subject matter is transmitted through the single lens of a special camera where it strikes a prism. One part of the light is passed through the prism and a green filter to a green-sensitive negative. The remainder of the light is reflected from the prism and absorbed by negatives sensitive to red and blue light. Each of the negatives is developed to produce new negatives which resemble black-and-white negatives. The Technicolor 3 color process has been available only in China since ca. 1980.
