Get more cinematic images out of your HERO5 Black or HERO6 Black camera with this Polar Pro Cinema Series Shutter Collection ND Filter Set for GoPro HERO5/6 Black. The three different strengths of ND, ND8, ND16, and ND32, provide 3, 4, and 5 stops of light reduction, respectively. With one of these filters installed, you can properly expose your image while maintaining a slower shutter speed for more cinematic motion blur. Introducing motion blur to lower frame-rate footage reduces the choppiness associated with fast shutter speeds. To maintain a high standard of image quality, the filters are multi-coated to prevent flaring, and actually fit in place of the cover lens of the HERO5 Black or HERO6 Black to further reduce aberrations and keep the image sharp. When not in use, the filters can be stored in the included slim case.
