NiSi Cine Filter Nano IR GND Soft 4x4"""" 1.2

NiSi Cine Filter Nano IR GND Soft 4x4" 1.2 – soft-edge graduated IRND that preserves neutral color

The NiSi Nano Soft-Edge Graduated IRND Filter for cine and still photography darkens specific areas of the frame, such as bright skies, while keeping the rest of the image at a normal exposure. It combines a soft-edged transition with coatings optimized for digital sensors to reduce infrared influence and maintain neutral color reproduction.

How this soft graduated IRND works

The filter is densest at its outer edge and gradually tapers to clear toward the middle. This smooth transition creates a soft, natural blend between the darker and clear portions of the frame. As a result, you can control highlights without altering exposure for the rest of the scene.

Optimized for digital sensors and color neutrality

This NiSi filter has been designed with digital sensors in mind. Each surface carries one layer of NiSi Optical Nano Coating that attenuates infrared light as well as visible wavelengths. That coating helps reduce color casts and supports truer blacks and cleaner tones when you extend exposure times or combine filters.

Key features

• Soft-edged graduated neutral density: Darkens bright areas of the image—such as skies—while leaving the remainder of the frame unaffected.
• IR attenuation on each surface: One layer of NiSi Optical Nano Coating is applied to every surface to attenuate infrared and visible light, helping to maintain color neutrality and suppress color casts.
• Optimized for digital sensors: The filter design promotes nearly flat attenuation across visible and infrared spectrums for improved results with modern digital cameras.
• Optical glass construction: Built from optical glass to provide clarity and strong color fidelity in captured images.
• Neutral density effect: Neutral density filtering does not affect overall coloration of the image, making the filter suitable for use with other filters without introducing color shifts.
• Soft-edged transition line: The filter features a soft-edged line of transition between the dense and clear areas for subtle blending.
• Scratch resistance: The filter surface resists scratches to preserve optical performance over time.
• Easy to clean: The coated surfaces are designed to be easy to clean when necessary.
• 4 mm thickness: The filter body is specified as 4mm thick.
• Leatherette pouch included: A leatherette pouch is supplied for storage and transport of the filter.

Practical use and compatibility

Use this soft-edge graduated IRND when you need to reduce exposure in part of the frame—especially skies—without affecting the rest of the image. The neutral behavior across visible and infrared wavelengths makes it suitable for digital capture workflows and for stacking with other filters while maintaining accurate color.

FAQ

Question: Will this filter change the color balance of my images?
Answer: No. The NiSi Nano Soft-Edge Graduated IRND is formulated to maintain color neutrality. Each surface includes a NiSi Optical Nano Coating that attenuates infrared light as well as visible wavelengths to suppress color casts and preserve accurate tones.

Question: Is this filter suitable for digital sensors?
Answer: Yes. The filter design has been optimized for use with digital sensors and promotes nearly flat attenuation across visible and infrared spectrums to deliver cleaner, truer blacks and reduce unwanted color shifts in digital workflows.

Question: What does the soft edge mean in practice?
Answer: The soft-edged transition provides a gradual blend between the darker and clear portions of the filter. This makes it easier to integrate darker skies or bright areas into the final exposure without a hard line or abrupt transition.

Question: What is included when I buy this filter?
Answer: The filter itself is constructed from optical glass, specified as 4 mm thick, and comes with a leatherette pouch for storage and transport. The surfaces include NiSi Optical Nano Coating for IR and visible attenuation, and the filter is described as scratch resistant and easy to clean.
