A CP filter is the most sought-after camera accessory for creatives, as it provides more contrast and vibrant, natural saturation for photos and videos. Typically, a CP filter is used for landscape shots with water, snow, ice, blue skies and foliage as it helps darken the sky, remove reflections and reduce unwanted glare from the scene. Designed specifically for direct replacement of the front lens element of the HERO9/10/11 Black cameras, each filter is made of CinemaSeries™ glass, which is so resistant and protected that it can withstand impact and rapid environments.
