NiSi’s Linear Polarizer uses the same high-quality optical glass as the rest of the NiSi line. This, coupled with Nitto Polarizer film, creates a filter with a 99.9% polarization rating. Each filter is precision ground and polished after the film is applied to ensure maximum sharpness. The edges of the filter are resin-sealed to keep moisture from entering the filter, improving durability.
Polarizers reduce the reflection on non-metallic surfaces to reveal the original color and texture of an object. Polarizers can also help to enhance the saturation of colors beyond that of normal vision. They are the most effective filter to improve the tone of the sky and are not easily imitated by post-production.
The NiSi Linear Polarizer Filter helps to reduce reflections and glare by filtering out the light on non-metallic surfaces. This light is often seen as a haze in landscape scenes. The linear polarizer passes light through the filter evenly which reduces this haze-like effect and a noticeable reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of skies and foliage.
Due to how the light is broken down and filtered with a linear polarizer, in-camera autofocus and exposure accuracy become skewed during use. This filter is recommended when not using in-camera exposure metering or autofocus.
The NiSi Cinema 4x4" range is perfect for pairing with the NiSi C4 Cinema Holder for a lightweight and quick to mount system for lenses with standard filter threads.
