ABSTRACT:
A photographic film is disclosed particularly adapted for underwater photography. The film is comprised of a film support, a blue recording layer unit capable of forming a yellow dye image, a green recording layer unit capable of forming a magenta dye image, and a red recording layer unit capable of forming a cyan dye image. At an exposure temperature of 5500.degree. K. and an optical density of 0.8 above minimum density the red recording layer unit exhibits a speed that is (T/10) log E greater than that of the green recording layer unit, where E is exposure in lux-seconds and T is the light transmission distance in meters through water required to match the speed of the red recording layer unit to the speed of the green recording layer unit, T being in the range of from 1.5 to 15 meters.
