The 100x150mm Reverse Nano IR Graduated Neutral Density filter from Nisi 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.

Sunset and sunrise photography sometime can be the challenge.

Nisi reverse ND filter is designed with dark area on the centre of the filter and gradually clearer to the top while the bottom part is clear preventing over exposure of skyline. 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 3.9 x 5.9″ / 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 recompose the photo for the best result.

By using neutral density filters the camera is vulnerable to infrared light which will cast the unwanted red colour to the photos when shooting at small apertures. 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 colour.
