The NiSi Nano IRND filter is a gray filter designed for landscape photographers, which is made of high-quality nano-coated optical glass. The gray filter can be used to reduce the light entering the camera and to use a larger aperture or a longer shutter speed than normal. The gray filter does not affect color reproduction and other filters can be used with it.
NiSi gray filters are designed for digital cells and they evenly reduce both visible light and infrared frequencies. The NiSi Optical Nano coating used on all filter surfaces enables very even filtering without color errors.
