Lee 4x4" CC20C (Cyan) Colour Compensating (Colour Correction) filters act specifically on relatively narrow bands of colour.

Lee 4x4" CC20C (Cyan) Colour Compensating (Colour Correction) filters act specifically on relatively narrow bands of colour. That is why they do not come in two colour variants (bluish and reddish) like conversion filters do. Instead, they come in three primary additive colours and their three secondary colours (which can be interpreted as the primary colours of subtractive mixing) - each colour comes in practical density steps. Lee colour compensating filters are made in the following increasing densities: 0.025(CC025), 0.05(CC05), 0.10(CC10), 0.15(CC15), 0.20(CC20), 0.25(CC25), 0.30(CC30), 0.40(CC40), 0.50(CC50). You can sandwich as many as three Lee polyester filters together without a noticeable loss of image quality. Some photographic situations require specific colour corrections. For example, when shooting daylight film under fluorescent lighting, some magenta correction is needed in order to remove the greenish tint that would otherwise appear.

Colour Compensating filters are made of gelatin and are available in the three primary colours: Red, Green, and Blue; and in the three secondary colours: Cyan, Magenta, and Yellow.

A typical designation for one of these filters is CC30M; The "CC" stands for Colour Compensating; The "30" stands for a density of 0.30 and the "M" is for magenta.
