  • Boosts colour and tonal saturation while reducing atmospheric haze
  • Delivers true colour reproduction without the warming cast common to other polarizers
  • Cine sealed edge technology protects the polarizing film from temperature shifts and condensation
  • Waterproof coating repels moisture for reliable performance in varied conditions

Cinema True Color Linear Polarizing Filter

The NiSi 4x5.65" True Color Linear Polarizing Filter is a cinema-grade glass filter designed for matte boxes accepting 4x5.65 inch panels. It targets cinematographers and photographers who need to suppress glare from non-metallic surfaces while preserving the scene's native colour balance.

Linear polarisation limits

Linear polarising filters work by blocking directionally polarised light reflected from surfaces such as water, glass or foliage. They are incompatible with through-the-lens metering and autofocus systems that rely on beam-splitters, so they suit cinema cameras or manual-exposure workflows rather than typical SLR or mirrorless stills bodies.

Cine sealed edge and coatings

Cine sealed technology blackens the glass edge to seal the polarising film against moisture ingress and temperature-induced delamination. A waterproof coating on both faces repels water and oil, easing field cleaning. The 4 mm substrate thickness provides rigidity for repeated insertion in standard 4x5.65" filter trays without flexing.

Questions about this item

Which size should I choose for my matte box?

The filter is made in the standard 4 x 5.65 inch cinema format, matching most professional matte boxes that accept 4x5.65" glass.

What does the True Color claim mean when I am shooting?

It removes the warm colour cast common on many polarisers, so skies and foliage keep their natural hue while glare is cut.

How does the linear polarisation work with my cinema camera?

It blocks reflected light from non-metallic surfaces, deepening blue skies and increasing contrast without affecting exposure metering on cinema cameras.
