The 100x150mm GND4 (0.6) Nano IR Hard Graduated Neutral Density Filter from NiSi is specially designed for landscape photographers. Made from high quality optical glass with nano coating, it preserves every bit of detail and will not affect the colour of your image. With a 0.6 density, it will provide a 2 stop reduction in light from entering the lens. It features a hard transition from being transparent on one end to being light-stopping on the other, making it a good choice when working with a horizon line or scenes where there is a hard transition between sky and foreground. Normally, when using a neutral density filter the camera is vulnerable to infrared light which can cause an unwanted red colour cast in images when shooting at small apertures. To prevent this, NiSi has added the infrared protection coating layer to this filter which helps to eliminate the infrared light through the lens to bring back the natural colour. This filter measures 100 x 150mm and is compatible with the Nisi 100mm filter holder or other 100mm Standard Filter Holder (Lee, Cokin or Formatt Hitech). The filter can be repositioned in the holder, allowing you to recompose the photo for the best result.
