The spectrozonal film is a color film developed in the Soviet Union , consisting of two layers. One layer is sensitive to infrared and is colored red during development. The second layer is panchromatic and is shown in positive green.
Spectrozonal films, for example, were on board the Russian RESURS-F satellites with the KFA-1000 camera system and will continue to be used.
