Overview

The NiSi Cinema 4x5.65" Hard-Edge ND 0.9 Filter is engineered for professional cinematography and videography where precise exposure balancing is essential. By reducing light transmission by 3 stops across the upper portion of the frame with a sharply defined transition line, this filter allows filmmakers to tame bright skies and high-contrast scenes without affecting exposure in the lower half of the image. This is particularly valuable when shooting exteriors where the dynamic range of a scene exceeds what a digital cinema camera can capture in a single exposure.

Built from optical glass with dual-sided nano coating, the filter maintains exceptional image sharpness and color fidelity while resisting the environmental hazards common on film sets—water droplets, oily fingerprints, and surface scratches. The nano coating also incorporates infrared light control, reducing IR pollution that can produce unwanted color shifts on digital sensors, especially when using higher-density ND filtration. The industry-standard 4x5.65-inch format slides into virtually any professional cinema matte box, making it a seamless addition to an existing filter workflow for narrative, documentary, and commercial production.

Pros & Cons

👍 Pros

  • Optical glass construction delivers high clarity and minimal image degradation.
  • Dual-sided nano coating provides water, oil, and scratch resistance for demanding on-set conditions.
  • 3-stop hard-edge graduation precisely controls exposure along a defined horizon line.
  • Industry-standard 4x5.65-inch cinema size fits most professional matte box systems.
  • Infrared light control reduces IR contamination that can cause color shifts in digital cinema cameras.

👎 Cons

  • Hard-edge transition is less forgiving on uneven horizons like cityscapes or mountain ranges.
  • The 4x5.65-inch cinema format is not compatible with standard still photography filter holders without an adapter.
  • Premium optical glass and coatings place this filter at a higher price point than resin alternatives.
  • A single 3-stop density may not be sufficient for extremely bright conditions, requiring stacking or a higher-density filter.

Frequently Asked Questions

An ND 0.9 density reduces light by 3 stops in the graduated area, allowing you to darken a bright sky by 3 stops while leaving the lower portion of the frame unaffected.
A hard-edge grad has a sharp, defined transition line between the dark and clear areas, making it best for scenes with a distinct, straight horizon line like seascapes or flat landscapes. A soft-edge grad has a more gradual blend.
NiSi's optical glass construction and nano-coating are designed to maintain color neutrality, minimizing unwanted color shifts in your footage.
The 4x5.65-inch cinema format is an industry standard and fits most professional matte boxes designed for that size, including systems from Tilta, Bright Tangerine, Wooden Camera, and others.
The dual-sided nano coating makes the filter resistant to water, oil, scratches, and fingerprints, which makes cleaning easier and protects the glass during on-set use.
