The Cokin Filter X005 Sepia is ideal for improving the contrast in your shots. Green and blue colours are filtered out of the image while the red colours are emphasized. Clouds are emphasised more, just as if a storm were brewing. This filter is also very effective when shooting in foggy conditions and for creating moonlight effects. In addition, this filter can also be used for infrared photography.
