A Kodak color compensating (CC)30M filter is a magenta gelatin filter used to correct or adjust color balance in photography by absorbing the green portion of the light spectrum. The "CC" stands for Color Compensating, the "30" indicates its density level, and the "M" signifies its magenta color. These filters are applied to correct color casts, such as those from fluorescent lights, or to balance light sources, and they require a small exposure increase.
Corrects color balance
- It addresses color casts by selectively absorbing light.
Attenuates green
- The magenta color of the filter absorbs green light, making it the opposite of green.
Compensates for light sources
- It can be used to correct the spectral quality of light sources that have deficiencies in color, like the greenish tint often seen with fluorescent lights.
Adds a magenta cast
- When placed in front of a lens, it can add a magenta cast to an image, which is used to counteract a green cast
