-The 4 x 4" Pro Indie HV Neutral Density Filter Kit will be of great use to anyone who enjoys shooting HD video with their DSLR or Camcorder.
-The filters are produced with high-quality Water White Glass for increasing color fidelity and sharpness. Water White Glass is characterized by a low iron, ultra clear glass that transmits 98% to 99% of light, and is anti-glare and ant-reflective coated.
-This ND Filter can work with the DSLRs that can shoot HD video and have a small 8-Bit color space.
-The ultimate purpose was to insure that the final color did not have a greenish/brown tint that resulted from other ND filters.
-Allows use of fast film in bright light
