The NiSi Cinema True Color Rotating PL for C5 Matte Box is an all-new rotating PL designed to fit the NiSi C5 Matte Box. The Polarizing Filter reduces reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. A polarizing filter arranges and filters this directionally polarized light perpendicularly to the reflected light, allowing for much of this light absorption. This results in a noticeable reduction of glare and reflections from non-metallic surfaces and increased saturation of skies and foliage. Our True Color PL removes the warm tone seen with other brands of polarizing filters and provides an accurate, true color representation of the scene. The amount of polarization is easily controlled by rotating the gear on the top of the filter or by mounting a motor using the 15mm rod holder to control the amount of polarization wirelessly.
