Lee Cyan 20 Poly CC Filter

Product Description

Lee 4x 4" 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 & reddish) like conversion filters do. Instead, they come in three primary additive colours & 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.
