NiSi Cine Filter True Color Polarizer 4×5,65″
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.
- This filter is recommended when not using in-camera exposure metering or autofocus. It is made using a process that involves laminating a layer of polarizing film between 2 pieces of optical glass. The glass layers are then ground flat to maintain image sharpness.
- Helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface.
- Polarizing filters arrange, and filter, directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of the light.
- Clears up haze in distant landscapes and provides more saturated, vivid colors.
- Strongest effect when used at a 90° angle from the sun.
- Recommended when not using in-camera exposure metering or autofocus.
- Scratch resistance
- Non-coated
- Leatherette pouch included for storage and transport
- Edge Seal process – Reduces the influence of temperature fluctuations and keeps out condensation.
