Circular polarizing filter for GoPro HERO 11/10/9. It enhances contrast and provides vibrant, natural saturation in photos while reducing unwanted glare from the scene. Suitable for GoPro Hero 9 to 12. The polarizing filter blocks light of a specific polarization direction, minimizing reflections on glass or water surfaces. Additionally, a polarizing filter better highlights colors or contrasts in landscape photography: the blue sky appears even bluer against the white clouds, and the colorful leaves in autumn look more intense and vibrant.
