The purpose of standard photographic neutral density filters is to allow the photographer greater flexibility to change the aperture, exposure time and/or blur of subject in different situations and atmospheric conditions. Instead of reducing the aperture to limit light, the photographer can add a ND filter to limit light, and can then set the shutter speed accordingly.Key Features:• Use larger aperture settings in bright light, permitting a shallow depth of field and beautiful background blur• Will not effect the color or detail of a scene• Eliminates overexposed & washed out images• 6 filters in 1 - Variable range: ND2- ND1000
