Three ND Strengths. The PolarPro Shutter ND Filter 3-Pack for GoPro HERO9 / HERO10 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. These filters are designed to mount onto the camera by replacing its original front lens elements. The filters’ anodized aluminum frames contain PolarPro CinemaSeries glass with a multi-coating that prevents flaring and protects against fingerprints, oils, and scratches. You can store the filters in the included slim storage case when not in use.
