FOTGA Nano 4x5.65 ND16 Square Neutral Density Filter, Multi-Layer Coatings MC ND 4-Stop ND1.2 HD Optical Glass ND Filter Description: A Neutral Density Filter or ND filter is a filter that reduces or modifies the intensity of all wavelengths or colors of light equally, giving no changes in hue of color rendition. It can be a colorless (clear) or grey filter. The purpose of a standard photographic neutral density filter is to reduce the amount of light entering the lens. Doing so allows the photographer to select combinations of aperture, exposure time and sensor sensitivity which would otherwise produce overexposed pictures. This is done to achieve effects such as a shallower depth of field and/or motion blur of a subject in a wider range of situations and atmospheric conditions. This FOTGA Nano ND filter is compatible with all brands of matte boxes and filter trays that fit the 4 x 5.65inch standard, such as Fotga DP500III DP3000 Matte box, Mini Lightweight Matte Box, JTZ DP30 Matte box.
