Square ND Filter
ND stands for Neutral Density. In photography and optics, a neutral density filter or ND filter is a filter that reduces or modifies intensity of all wavelengths or colors of light equally, giving no changes in hue of color rendition. The purpose of a standard photographic neutral density filter is to allow the photographer greater flexibility to change the aperture, exposure time and/or motion blur of subject in different situations and atmospheric conditions.
