Cokin and OmegaBrandess Introduce NUANCES GND Filters

The dark side has never been so attractive. Hampstead, MD — Only a few months after having introduced NUANCES Full ND filters – the best Neutral Density filters available, Cokin and OmegaBrandess are proud to announce NUANCES Graduated Neutral Density (GND) filters. Cokin states that their biggest challenge has been to adapt their coating technology to make it graduated. A nano-metallic alloy...
