NiSi Cine Filter Nano IR GND Soft 4x4"""" 0.3

NiSi Cine Filter Nano IR GND Soft 4x4" 0.3 — Soft-Edge Graduated IRND to darken bright skies while preserving color neutrality

This NiSi Cine Nano IR GND Soft filter (4x4" 0.3) darkens specific areas of your frame—most commonly bright skies—while keeping the rest of the exposure unchanged. The filter is densest at the edge and tapers to clear toward the center, with a soft-edged transition line between dense and clear areas to create a smooth, natural gradation in exposure.

Optimized for digital sensors and balanced visible/infrared attenuation

NiSi designed this graduated neutral density filter for use with digital sensors. Each surface receives one layer of NiSi Optical Nano Coating to promote nearly flat attenuation across visible and infrared wavelengths. As a result, the filter helps maintain color neutrality and reduces the risk of infrared-induced color casts that can appear during longer exposures.

Construction and handling

The filter is constructed from optical glass to support image clarity and accurate color rendition. It features scratch resistance and an easy-to-clean surface, helping you keep the filter in working condition with routine maintenance. A leatherette pouch is included for safe storage and transport when you are on location or moving between shoots.

Key features

• Darkens bright areas of an image, such as skies, while leaving the remainder of the frame unaffected.
• Soft-edged line of transition between the dense and clear areas for natural gradation.
• Optimized for digital sensors with nearly flat attenuation of visible and infrared light.
• Each surface includes one layer of NiSi Optical Nano Coating to attenuate infrared and visible wavelengths and to suppress color casts during increased exposure times.
• Constructed from optical glass for clarity and color fidelity.
• Neutral density filter does not affect the coloration of the image, making it suitable to use together with other filters.

Frequently asked questions

Question: What does this graduated filter do?
Answer: The filter darkens specific parts of the image—typically bright skies—while leaving other areas at normal exposure. Its soft-edge transition creates a smooth change from dark to clear, useful for landscape and outdoor scenes.

Question: How does the Nano coating benefit my images?
Answer: Each surface has a layer of NiSi Optical Nano Coating that attenuates both infrared and visible light. This helps maintain color neutrality across the spectrum and reduces infrared-related color casts that can occur with digital sensors, especially during longer exposures.

Question: Will this filter change the color of my image?
Answer: Neutral density filters, including this NiSi Nano Soft-Edge GND, do not affect image coloration. The Nano coating further helps to keep colors true by reducing infrared influence.

Question: Can I use this filter with other filters?
Answer: Yes. Because the filter does not alter color and is constructed for neutrality, it is suitable for use in combination with other filters.

Question: How should I care for the filter?
Answer: The filter is scratch-resistant and easy to clean. Use standard lens-cleaning methods to remove dust or smudges, and store the filter in the included leatherette pouch when not in use to protect the surface.
