NiSi Cine Filter Nano IR GND Soft 6x6"""" 0.9

NiSi Cine Filter Nano IR GND Soft 6x6" 0.9 — Soft-edge graduated IRND for controlling bright skies

The NiSi Nano Soft-Edge Graduated IRND Filter helps you darken specific areas of a frame, such as bright skies, while keeping other regions at a normal, unaffected exposure. The filter is densest at one edge and tapers to clear toward the center, with a soft-edged transition line between the dense and clear areas.

Designed for digital sensors and color neutrality

NiSi optimized this filter for use with digital camera sensors. Each surface receives one layer of NiSi Optical Nano Coating to attenuate infrared light as well as visible wavelengths. As a result, the filter promotes nearly flat attenuation across the visible and infrared spectrums to reduce color casts and preserve truer blacks during longer exposures.

Key features

• Constructed from optical glass for clarity and color fidelity.
• Graduated neutral density design darkens bright areas (for example, skies) while leaving the remainder of the frame unaffected.
• Soft-edged line of transition between the dense and clear areas for smooth blending.
• Neutral density effect does not affect coloration of the image, making the filter suitable for use with other filters.
• Each surface includes one layer of NiSi Optical Nano Coating that attenuates infrared light as well as visible wavelengths to maintain color neutrality and suppress color casts during increased exposure times.
• Scratch resistance for greater durability.
• Easy to clean for convenient maintenance on set or in the field.
• The filter is 4mm thick.
• Leatherette pouch included for storage and transport.

How the soft-edge GND works

The filter is densest at its edge and gradually becomes clear toward the middle. This graduated density lets you reduce brightness in a specific portion of the frame while maintaining normal exposure elsewhere. Use the soft-edged transition to blend the darker and clearer areas smoothly, which is especially useful when the horizon or subject transitions are not perfectly straight.

Practical use cases

• Darkening bright skies to retain detail while keeping foreground exposure natural.
• Balancing scenes with large exposure differences between sky and ground without affecting midtones.
• Combining with other filters since the ND effect maintains neutral coloration.

Care and handling

Handle the filter with care to preserve the optical surfaces and Nano coating. The filter’s scratch resistance and easy-to-clean surfaces simplify maintenance, and the included leatherette pouch provides protection during storage and transport.

FAQ

Question: How does the NiSi Nano Soft-Edge GND affect image color?
Answer: The filter is designed to be color neutral. Each surface receives a NiSi Optical Nano Coating that attenuates infrared as well as visible wavelengths to minimize color casts and help maintain true blacks.

Question: Can I use this filter with other filters?
Answer: Yes. The neutral density design does not affect image coloration, making it suitable for use alongside other filters.

Question: What types of scenes benefit most from the soft-edge GND?
Answer: Scenes with bright skies or other localized bright areas benefit most, especially when you want to retain detail in the sky while keeping the foreground or other parts of the frame at normal exposure.

Question: What is included for storage and transport?
Answer: The filter comes with a leatherette pouch for safe storage and convenient transport.
