The Nisi 150x170mm Nano IR Soft Graduated Neutral Density Filter ND16 4 Stop is specially designed for landscape photographers. This filter is made from high quality optical glass (not resin) with nano coating to prevent losing any single bit of detail. The filter is designed with dark area on the top and gradually to clear at the bottom preventing over exposure of skies. Neutral density filters do not affect the coloration of the image and the 1.2 density provides a 4 stop reduction in light from entering the lens. This filter measures 150 x 170mm and is compatible with the NiSi 150mm filter holder System or other 150mm Standard Filter Holder (Lee, Cokin or Formatt Hitech). The filter can be repositioned in the holder allowing recompose the photo for the best result.
By using neutral density filter the camera is vulnerable to infrared light which will cast the unwanted red color to the photos when shooting at small aperture. Nisi added the infrared protection coating layer to this filter which help to eliminate the infrared light through the lens to bring back the nature color.
