The Nano IR 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. Neutral density filters do not affect the coloration of the image. The filter’s are compatible with NiSi Filter Holder’s or other Standard same size Filter Holder’s (Lee, Cokin or Formatt Hitech).

By not using a neutral density filter the camera is vulnerable to infra-red light which will cast the unwanted red colour to the photos when shooting at a small aperture. NiSi added the infra-red protection coating layer to this filter which helps to eliminate the infra-red light through the lens to bring back the natural colour.

The purpose of a standard photographic neutral-density filter is to reduce the amount of light entering the lens. Doing so allows the photographer to select combinations of aperture, exposure time and sensor sensitivity which would otherwise produce overexposed pictures. This is done to achieve effects such as a shallower depth of field or motion blur of a subject in a wider range of situations and atmospheric conditions.

For example, one might wish to photograph a waterfall at a slow shutter speed to create a deliberate motion blur effect. The photographer might determine that to obtain the desired effect a shutter speed of ten seconds was needed. On a very bright day, there might be so much light that even at minimum ISO and a minimum aperture, the ten-second shutter speed would let in too much light and the photo would be overexposed. In this situation, applying an appropriate neutral-density filter is the equivalent of stopping down one or more additional stops,allowing for the slower shutter speed and the desired motion-blur effect.
