Optical Glass, Optimal Results. This 4 × 5.6 PolarPro ND32 Neutral Density Filter (5-Stop) slides right in to most standard matte/zip boxes to provide 5-stops of exposure reduction, leaving you with a darker image area. ND filters are notorious for allowing finer, more in-tune control of shutter speeds and aperture settings.

Prevention and Protection. This filter comes equipped with a multi-coating to prevent scratches, oil, water, ghosting, and reflections. Around the trim of the glass, an aluminum frame protects the filter when adding it to your matte box.
