NiSi Square Nano IRGND Soft 75X100mm GND8 0.9

NiSi Square Nano IRGND Soft 75x100mm GND8 0.9 – Soft Graduated ND with Infrared Protection

This NiSi Square Nano IRGND Soft filter is made for landscape photographers who need controlled exposure between sky and land. It places a darker area at the top and transitions gradually to clear at the bottom, helping to prevent overexposed skies while retaining detail in the darker foreground.

Soft graduated density for challenging light transitions

The soft transition design works especially well when the border between bright and dark areas is not clearly defined. For example, you can use it in mountainous scenes where peaks, ridges and clouds create gradual changes in brightness. By positioning the darker region over the sky, the filter helps balance exposure across the scene without producing a hard line.

High-quality optical glass and nano coatings

NiSi manufactures this filter from high quality optical glass, not resin. In addition, the filter features a nano coating that preserves fine detail. The nano coating also makes the surface water and oil repellent, which helps keep the filter cleaner during outdoor shoots.

Infrared protection to restore natural color

Neutral density filters can allow infrared light to affect the image, which may cause an unwanted red cast when shooting at small apertures. NiSi added an infrared protection coating layer to this filter to reduce infrared transmission and help bring back natural color in those situations.

Repositionable for precise composition

The filter can be moved within a compatible holder so you can recompose after placing the filter. This repositioning ability lets you align the graduated transition with the scene for the best visual result, giving you greater control over final composition and exposure balance.

FAQ

Question: What scenes is this filter best suited for?
Answer: This soft graduated filter is designed for landscape scenes where the transition between bright sky and darker foreground is gradual, such as mountainous areas. It reduces sky overexposure while preserving foreground detail.

Question: Will this filter change the colors in my image?
Answer: Neutral density filters do not affect the coloration of the image. Additionally, the infrared protection coating on this filter helps prevent infrared-induced red casts that can occur at small apertures, helping to maintain natural color.

Question: What is the filter made of and how does the coating help?
Answer: The filter uses high quality optical glass rather than resin. The nano coating on both sides preserves fine detail and provides water and oil repellence, which improves durability and ease of cleaning in outdoor conditions.

Question: Can I adjust the position of the transition after mounting?
Answer: Yes. The filter can be repositioned inside a compatible holder, allowing you to recompose and align the graduated transition with the scene for optimal exposure control.

Question: Which density strengths are available for this size?
Answer: The 75x100 mm NiSi Nano IR Soft GND filters are available in 2-stop and 3-stop strengths; this listing is identified as GND8 0.9.
