NiSi Cine Filter Nano IR GND Soft 4x5.65" 0.3 – Soft-Edge Graduated ND to Darken Bright Areas

The NiSi Cine Nano IR GND Soft 4x5.65" 0.3 filter darkens specific bright areas of an image, such as skies, while leaving the rest of the frame unaffected. It achieves this with a soft-edged transition from dense to clear, so you can retain natural exposure in the non-affected regions.

Purpose and use

This graduated neutral density filter helps you control exposure across a scene. Use it when you want to reduce brightness in one area—commonly the sky—without changing exposure for foreground elements. The soft-edged transition suits scenes with uneven horizons or where a hard line would appear unnatural.

Optimized for digital sensors and infrared control

The filter has been optimized for use with digital sensors. Additionally, NiSi applies one layer of its Optical Nano Coating to each surface of the filter. This coating promotes nearly flat attenuation of both visible and infrared light. As a result, the filter helps maintain color neutrality and suppresses infrared-induced color casts that can appear with longer exposures.

Optical construction and image quality

• Constructed from optical glass to deliver clarity and color fidelity.
• Neutral density design does not affect the coloration of the image, preserving natural colors.
• Soft-edged line of transition between the dense and clear areas for smoother blends in the frame.
• Filter remains effective when combined with other filters, making it suitable for multi-filter setups.

Durability and handling

• Each surface includes one layer of NiSi Optical Nano Coating that attenuates infrared and visible wavelengths to maintain color neutrality and suppress color casts.
• Scratch resistance provides added durability during use in the field.
• Easy to clean, which simplifies maintenance between shoots.
• The filter is 4mm thick, contributing to its robustness.

What’s included

The filter ships with a leatherette pouch for storage and transport, helping you protect the glass when not in use.

FAQ

question: How does the soft-edge graduated density appear in the image?
Answer: The filter is densest at the edge and tapers to clear by the middle, creating a soft-edged transition that darkens bright areas like skies while keeping the rest of the frame unaffected.

question: Will this filter change my image colors?
Answer: No. The neutral density design, together with NiSi’s Optical Nano Coating on each surface, maintains color neutrality and reduces infrared-induced color casts, so the filter does not affect image coloration.

question: Is this filter suitable for digital cameras and longer exposures?
Answer: Yes. It has been optimized for digital sensors and its coating attenuates infrared as well as visible light, which helps preserve true blacks and suppress color casts during increased exposure times.

question: How should I care for the filter during field use?
Answer: The filter offers scratch resistance and is easy to clean. When not in use, store it in the supplied leatherette pouch to protect the glass and coatings.
