Cokin Z703 Cyan Color Correction Filter CC20C - 4x4"/100x100mm Z-Pro Series

· Color Compensating Filters - Control color by attenuating principally the red, green, or blue part of the spectrum. They can be used to make slight changes in the color balance of images recorded on color films, or compensate for deficiencies in the spectral quality of a light source. These filters will work perfectly with color temperature meters where even slight variences of color will cause a problem.
