NiSi Cine Filter Nano IR GND Soft 4x5.65"""" 0.6 – Soft-edge graduated ND to darken bright skies

This NiSi Nano Soft-Edge Graduated IRND filter darkens specific areas of an image—most commonly bright skies—while leaving the rest of the frame at a normal exposure. The filter is densest at the edge and tapers to clear by the middle, with a soft, gradual line of transition between the dense and clear areas. Photographers and filmmakers use it to balance exposure between sky and foreground without affecting the unaffected regions.

Designed for digital sensors and color neutrality

The filter’s design has been optimized for use with digital sensors. It promotes nearly flat attenuation across both visible and infrared wavelengths. To maintain color neutrality and suppress color casts that sometimes occur with long exposures, one layer of NiSi Optical Nano Coating is applied to each surface of the filter. As a result, the filter helps deliver cleaner, truer blacks when used in-camera.

How the soft-edge GND works in practice

Use the soft-edge graduated density to control bright areas that sit near the horizon or within a scene where a hard line would be noticeable. Because the density tapers gradually from the edge toward the middle, the transition appears natural in scenes with irregular horizons or where a gentle blend is needed between sky and foreground. At the same time, the rest of the image remains unaffected by the neutral density effect.

Key features

• Optimized for digital sensors: The filter is designed to provide nearly flat attenuation of visible and infrared light for improved color neutrality with digital capture.
• NiSi Optical Nano Coating: Each surface includes one layer of NiSi Optical Nano Coating that attenuates infrared light as well as visible wavelengths to reduce color casts and maintain accurate tones.
• Soft-edge graduated density: The densest area sits at the edge and tapers to clear by the middle, creating a soft-edged transition that blends smoothly in many scenes.
• Maintains coloration: Neutral density action does not affect the coloration of the image, making this filter suitable to use alongside other filters without introducing unwanted color shifts.
• Optical glass construction: Built from optical glass for clarity and color fidelity to preserve image quality.
• Scratch resistance and easy to clean: Surface properties help protect the filter and simplify maintenance during shoots.
• 4 mm thickness: The filter’s thickness is specified at 4 mm.
• Storage included: A leatherette pouch is included for storage and transport of the filter.

Use cases

Use this soft-edge GND when you need to reduce overexposed skies or bright background areas while keeping foreground exposure unchanged. It works well for landscape scenes with soft or irregular horizons, for filmmaking scenarios where smooth blending is essential, and any digital workflow requiring infrared attenuation to avoid color casts.

FAQ

Question: What does "soft-edge" mean for this graduated filter?
Answer: Soft-edge means the filter’s density transitions gradually from the darkest edge toward the clear center, creating a smooth blend. This makes it suitable for scenes with irregular horizons or where a hard transition would be visible.

Question: Will this filter change the colors in my image?
Answer: No. Neutral density action does not affect image coloration. Additionally, the NiSi Optical Nano Coating on each surface attenuates infrared as well as visible wavelengths to help prevent color casts, especially during longer exposures.

Question: Is this filter suitable for digital cameras?
Answer: Yes. The filter’s design has been optimized for use with digital sensors to provide nearly flat attenuation across visible and infrared light, helping maintain color neutrality with digital capture.

Question: What is included with the filter for storage and transport?
Answer: The filter comes with a leatherette pouch for storage and transport, helping protect the optical surface when not in use.
