Freewell ND64/PL is designed for situations with very intense light, when you need to maintain correct exposure without compromising image quality. The combination of an ND64 neutral density filter and a CPL polarizing layer makes filming in direct sun easier while also helping to prevent distracting reflections.
The filter effectively suppresses reflections from glass, water surfaces, and other glossy surfaces, so the resulting footage looks richer and more natural. At the same time, it helps protect bright areas from overexposure and maintain control over the bright parts of the scene.
A major advantage is also the lightweight construction, which does not burden the internal stabilization of the Insta360 Luna Ultra camera, making it suitable even for dynamic shots.
