This Cokin Z-Pro 003 Red filter is ideal for strong contrast improvement since it absorbs green and blue completely and enhances red. In addition to contrast control, red filters enhance skin tones, tonal corrections and are effective for more dramatic landscapes. When combined with a polarizer, the resulting image will increase the saturation of clouds making it appear that a storm is threatening.
The Z-PRO Series is recommended for focal lengths of 20mm onwards (in the 35mm format). This filter is made of CR39 Resin which is a reputable lightweight and unbreakable optical material also used for ophthalmic glasses.
