The NiSi Nano Vertical Soft-Edge Graduated IRND filter darkens specific parts of the frame while leaving other areas at normal exposure. It is densest at the edge and tapers to clear by the middle, with a soft-edged transition between the dense and clear regions. In practice, this makes it useful for controlling bright skies or other localized highlights without affecting the remainder of the image.
The filter’s design has been optimized for use with digital sensors. Additionally, it promotes nearly flat attenuation across visible and infrared wavelengths. As a result, it helps maintain color neutrality and avoid color casts that can occur with increased exposure times. To support this performance, each surface of the filter carries one layer of NiSi Optical Nano Coating that attenuates infrared light as well as visible light.
Use this vertical soft-edge graduated filter when you need to reduce brightness in a section of the frame—most commonly skies—while preserving normal exposure elsewhere. Because the filter maintains neutral color balance and is compatible with other filters, you can combine it with polarizers or other glass-based filters without introducing noticeable color shifts.

Question: Will this filter change the color of my image?
Answer: No. The NiSi Nano IR GND V-Soft is designed not to affect coloration. The optical glass construction and NiSi Optical Nano Coating help maintain neutral colors and suppress color casts.
Question: How does the soft-edge differ from a hard-edge graduated filter?
Answer: The soft-edge transition provides a gradual blend between the darkened and clear areas, which is especially useful for scenes with uneven or soft horizons—such as clouded skies—where a hard line would be noticeable.
Question: Can I use this filter together with other filters?
Answer: Yes. The filter does not affect coloration and is specifically noted as ideal for use with other filters, allowing for stacking without introducing significant color shifts.
Question: What does the NiSi Optical Nano Coating do?
Answer: Each surface includes one layer of the NiSi Optical Nano Coating, which attenuates infrared as well as visible wavelengths. This helps preserve color neutrality and achieve cleaner, truer blacks during longer exposures.
Question: What comes with the filter and how is it protected?
Answer: The filter includes a leatherette pouch for storage and transport. The glass is scratch-resistant and easy to clean, helping protect your investment during regular use and handling.
