The NiSi Cinema 4×5.65″ Enhanced Rotating CPL Filter helps to reduce 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 the absorption of much of this light. This results in a noticeable reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of skies and foliage.
NiSi designed their new rotating circular Polariser with the cinematographer in mind. The filter fits into a standard matte box tray and uses a 0.8 gear to turn a circular polariser in the assembly. This design makes it easy to find the polarisation you want with the turn of a finger.
The Rotating Circular Polariser can significantly improve efficiency on time-sensitive shoots, making it a powerful tool for videographers and cinematographers.
Weather isn’t a problem with the NiSi Rotating Circular Polariser. Its double-sided waterproof coating lets water slide right off, leaving no trace on the filter. It also means that less dust and dirt will stick to the filter, making it easier to clean. The edge of the Polariser is sealed to keep moisture from entering the filter.
The Rotating Enhanced CPL uses a unique nano-coating that amplifies the effect the polariser has on colours. It helps to boost colour saturation and make the skin tones more natural.
