Three ND Strengths. The PolarPro Shutter Collection ND Filter Set for HERO8 Black (Set of 3) includes ND8, ND16, and ND32 filters, which provide 3, 4, and 5 stops of light reduction, respectively. You can use these filters to properly expose your images while maintaining a lower shutter speed for cinematic motion blur. Using motion blur on lower frame-rate footage helps reduce the choppiness you get from shooting at fast shutter speeds.

Easy Installation and High-Quality Construction. This set is part of the HotSwap magnetic filter system and includes a snap-on magnetic base that attaches to the HERO8 and lets you quickly swap out the filters. The filters and base use very strong magnets that’ll keep everything in place, even when you’re shooting in adverse conditions like high-velocity wind or high-vibration motorsports. The filters are multi-coated to prevent flaring, and they boast anodized aluminum frames. You can store the filters in the included slim storage case when not in use.
