It is essentially a darkened piece of glass (or resin) that is designed not to change anything other than the quantity of light that passes through it.Other factors such as the color of the light or polarization of the light should not be affected.This allows for creative effects such as using a wider aperture (for depth of field effects) or a longer shutter speed (for time-based effects) than would not be possible otherwise. They are most useful in bright conditions where there is a lot of available lightProduct NameNeutral Denisity Filter Optical Glasses Filters Square ND Filter ND2 ND4 ND8 ND64 ND32000 for PhotographyMaterialglassDimensionAs DesignDimension Tolerance+-0.1mmSurface Quality40/20Clear Aperture>90%ND2-32000Transmittance50%,25%,0.1%,0%...ShapeRound and squareBevelregular.We offer customized service for Nd Filters ,The square and round shapes are both available.Because of different denisity, the thickness of each type may be has a little different ,please noticedOther ItemsFactory informationChangchunYutai Optics Co.,Ltd.is a manufacturer with ISO9001 certification.
