NiSi Cine Filter Nano IR GND Hard 4x5.65"""" 0.3

NiSi Cine Filter Nano IR GND Hard 4x5.65" 0.3 – Hard-edge graduated density for clearly defined horizons

This NiSi Cine Nano IR GND Hard filter darkens specific areas of your image, such as bright skies, while leaving the rest of the frame unaffected. The filter is densest at the edge and tapers to clear toward the middle, producing a sharp, hard-edged transition between the dense and clear areas. Photographers and filmmakers commonly use it when the separation between bright and dark regions is well defined, for example at the horizon or the boundary between sea level and sky.

Designed for digital sensors and accurate color

The filter’s design optimizes performance with digital sensors. NiSi applies one layer of its Optical Nano Coating to each surface of the filter. This coating attenuates infrared light as well as visible wavelengths, which helps maintain color neutrality and suppress color casts that can occur with increased exposure times. As a result, the filter supports cleaner, truer blacks and consistent color reproduction across the frame.

Construction, durability and included accessories

NiSi constructs this graduated neutral density filter from optical glass to preserve clarity and color fidelity. The filter includes scratch resistance and a leatherette pouch for safe storage and transport. The filter is 4mm thick and built to integrate with other filters without affecting image coloration, making it suitable for layered filter setups.

Key features and benefits

• Hard-edge graduated neutral density: Darkens bright areas of an image, such as skies, while leaving other regions unaffected.
• Sharp transition line: The filter provides a clearly defined edge between dense and clear areas, useful for scenes with distinct horizons.
• Color-neutral performance: The filter does not affect the coloration of the image, allowing reliable results when used with other filters.
• IR attenuation via Nano Coating: Each surface includes one layer of NiSi Optical Nano Coating to attenuate infrared as well as visible light, helping to eliminate color casts during long exposures.
• Optical glass construction: Built from optical glass for clarity and accurate color reproduction.
• Scratch resistance: The surface treatment improves durability for field use.
• Thickness: This filter is 4mm thick, contributing to its rigidity and handling.
• Storage: A leatherette pouch is included for protection and transport.

FAQ

Question: When should I choose a hard-edge GND like this NiSi filter?
Answer: Choose this hard-edge GND when the boundary between bright and dark areas is sharply defined—such as a flat horizon, coastline, or other straight-line separations—because the filter’s sharp transition aligns well with those scenes.

Question: Will this filter change the color balance of my images?
Answer: No. The filter is designed not to affect image coloration. Additionally, the NiSi Optical Nano Coating attenuates infrared and visible wavelengths to reduce color casts, helping you maintain neutral color balance even during longer exposures.

Question: Can I stack this filter with other filters?
Answer: Yes. The filter does not affect coloration and is suitable for use with other filters. Ensure your holder or matte box can accommodate the combined thickness when stacking.

Question: How does the Nano Coating help my footage or photos?
Answer: The Nano Coating attenuates infrared light as well as visible light. This promotes nearly flat attenuation across both spectrums, which reduces infrared-induced color shifts and helps maintain accurate colors and truer blacks during extended exposures.

Question: What protection and handling does the product include?
Answer: The filter is constructed from optical glass with scratch-resistant treatment and comes with a leatherette pouch for storage and transport, helping protect the filter between uses.
