The Nano IR Medium 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. 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. This filter can be repositioned in the holder allowing recompose the photo for the best result.
A neutral density filter with a medium-edged line of transition is particularly useful for images that feature buildings, mountains and other elements that protrude into the skyline.
By using neutral density filter the camera is vulnerable to infrared light which will cast the unwanted red color to the photos when shotting 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.
