NiSi Cine Filter Nano IR GND Soft 4x4"""" 0.6 – Soft-Edge Graduated ND to Darken Bright Areas Like Skies

The NiSi Cine Nano IR GND Soft filter helps you darken specific parts of a scene—most commonly bright skies—while keeping the rest of the frame exposed normally. It transitions from a dense edge to a clear middle with a soft, gradual line, allowing smooth blending in-camera.

Optimized for digital sensors and color neutrality

This filter has been designed for digital sensors to provide nearly flat attenuation across visible and infrared wavelengths. In practice, that means it reduces infrared contamination and limits color casts that can appear during longer exposures.

To preserve accurate colors and cleaner blacks, NiSi applies one layer of its Optical Nano Coating to each surface of the filter. The coating attenuates both infrared and visible light to help maintain color neutrality.

How the soft-edge graduated density works

The filter is densest at one edge and gradually becomes clear toward the center. Because the transition is soft-edged, the change between dark and clear areas blends smoothly. You can use this to control bright elements without affecting the exposure in the remainder of your image.

FAQ

Question: Will this filter change the colors in my image?
Answer: No. Neutral density filters do not affect image coloration, and this NiSi Nano IR coating further attenuates infrared light to help maintain color neutrality and reduce color casts.

Question: What does "soft-edge" mean and when should I use it?
Answer: Soft-edge means the density tapers gradually from a dark edge to a clear center with a blended transition. Use it when the boundary between bright and dark areas is irregular or when you need a gentle, natural-looking exposure balance—such as scenes with uneven horizons or variable cloud cover.

Question: Can I combine this filter with other filters?
Answer: Yes. Because the filter is neutral in coloration and constructed from optical glass, it is suitable for use alongside other filters without introducing noticeable color shifts.

Question: Is the filter durable and easy to maintain?
Answer: The glass features scratch resistance and an easy-to-clean surface. The package also includes a leatherette pouch for safe storage and transport.

Question: How does the NiSi Optical Nano Coating benefit my images?
Answer: The coating attenuates both infrared and visible wavelengths across each surface, which helps eliminate infrared-induced color casts and supports truer blacks and more neutral tones, especially during longer exposures.
