NiSi Cine Filter True Color Polarizer 4x5,65"
A polarizing filter arranges 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.
A linear polarizer differs from a circular polarizer in that it does not contain an additional quarter wave plane.
The addition of a quarter wave plane is to circularly polarize linearly polarized light for the use of auto focus and exposure functions.
Due to how the light is broken down and filtered with a linear polarizer, in-camera auto focus and exposure accuracy become skewed during use.
When the light becomes circularly polarized, it permits the use of these functions.
