Neutral Density ( ND) Filters are used to reduce or modify intensify of all wavelengths of light equally, giving no changes in hue of colour rendition. The purpose of a standard photographic neutral density filters are to give greater flexibility to change the aperture, exposure time andor motion blur of subject in different situations and atmospheric conditions.
