Cokin Z-Pro Nuances Extreme Reverse Graduated ND4 2 Stops

The Cokin Z-Pro Series Nuances Extreme Glass Reverse Graduated ND4 filter balances exposure between the middle at edge of an image, reducing exposure by 2 stops at the densest part in the middle. Made from Schott B270 mineral glass, renowned for its high light transmittance, its internal and external reflections are minimised by Cokin’s new nano metallic alloy coating process. The transition between ND and clear areas is soft, and it's especially useful for sunsets and other images where there is extra brightness at the horizon, but some holding back of sky or foreground in required. 101 x 143 x 2.3mm, for Cokin Z-Pro (L Series), Lee, Hitech or other compatible filter holders.
