The NiSi Cinema 4×5.65” True Color Rotating PL Polarising Filter reduces reflections and glare by filtering out light that has become polarised due to reflection from a non-metallic surface. A polarising filter arranges and filters this directionally polarised 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 an increase in the saturation of skies and foliage.
The True Color PL removes the warm tone seen with other brands of polarising filters and provides an accurate, true color representation of the scene.
The rotating Polariser was designed with the cinematographer in mind. The filter is 6mm thick and fits into a standard matte box tray. The PL features an M0.8 focus control gear, allowing adjustments with an attached small motor or manually. The aluminium frame is light, stable, and durable and includes a 1/4″ thread to allow the PL to be used with a magic arm. Included in the box is a 15mm support rod. The edge of the Polariser is sealed to keep moisture from entering the filter.
The Rotating PL Polariser can significantly improve efficiency on time-sensitive shoots, making it a powerful tool for videographers and cinematographers.
