The NiSi 100x100mm True Color Square Polarizer is designed to reduce glare and reflections from non-metallic surfaces, increase saturation and vibrancy in the sky and foliage while ensuring true color reproduction is at its best by eliminating the warming effect that many polarisers create. Our True Color PL removes the warm tone seen with other brands of CPL filters and provides a closer true color representation of the scene. NiSi's 100x100mm True Color Square Polarizer utilizes Cine seal technology which blackens the edge of the glass for added durability. This technology reduces the influence of temperature fluctuations and keeps out condensation.
Polarizing Filters helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. The light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. 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, foliage, and allows the camera to capture what is under the surface of shallow water.
The NiSi 100x100mm True Color Square Polarizer is made of the highest quality optical glass, the polarising film is the best on the market and offers a very high polarisation close to 100%. This square filter offers linear polarisation and should be used on holders for 100mm and 2mm thick filters.
