The NiSi Cinema 4×4″ Nano IR Neutral Density 0.9 Filter (3 Stop) creates a darkening of the entire image by 3 stops, allowing you to compensate for bright conditions whilst keeping your Aperture, Shutter speed and iso where you need them to be. The IR Coating eliminates any unwanted colouration of the image when used in conjunction with other filters. In order to remove any colour cast and keep the Blacks as rich and true as possible, one layer of NiSi Optical Nano Coating is applied to each of this filter’s surfaces along with the IR coating to provide the highest colour accuracy as possible. This coating, coupled with high-quality optical glass and strict manufacturing standards, give you accurate colour, extreme sharpness making it perfect for today’s high-res. cameras.
