The NiSi 100x100mm Nano IR Neutral Density filter is specially designed for landscape photographers. This filter is made from high quality optical glass (not rasin) with nano coating to prevent losing any single bit of detail. Neutral density filters do not affect the coloration of the image. This filter measures 100mm x 100mm and is compatible with the Nisi 100mm filter holder.

By using neutral density filter the camera is vulnerable to infrared light which will cast the unwanted red colour 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 colour.
