NiSi Square Nano IRND 75x80mm ND32000 15Stops

NiSi Square Nano IRND 75x80mm ND32000 (15 Stops) – Nano-coated IR protection for true-to-life colors

This NiSi Square Nano IRND 75x80mm ND32000 filter provides 15 stops of neutral density attenuation for extended exposure control. It uses high-definition optical glass and NiSi’s Nano IR coating to reduce infrared contamination and maintain natural, vibrant color when you lengthen exposure times.

Designed for landscape photographers and long exposures

Photographers who work with long exposures, especially in landscape photography, benefit from this filter’s dense light reduction. You can lengthen shutter speeds to create motion blur, smooth water, or capture creative effects while preserving image detail. Because the filter is made from optical glass rather than resin, it helps retain high definition and fine detail in the image.

IR protection and colour fidelity

Neutral density filters block visible light but can allow infrared (IR) light to pass through. At small apertures that IR leakage can cause a red cast and change the perceived color balance of the image. NiSi adds an infrared protection coating to this filter to reduce IR contamination and bring back natural color in your photos. The double-sided Nano Coating further reduces reflections and helps maintain accurate colour rendition.

Key features

Available densities

NiSi offers these square Nano IR Neutral Density filters in the 75x80mm size across a range of stopping powers: 3 stop, 6 stop, 10 stop and 15 stop (ND32000). This listing describes the 15-stop ND32000 option, which provides substantial light reduction for long-exposure work.

How it performs in practice

The combination of high-definition optical glass and double-sided nano coating minimizes reflections and preserves fine detail. The IR protection layer specifically targets unwanted infrared light that can otherwise shift colours at small apertures. The result is a neutral density filter that lets you extend exposure time while keeping colours natural and image sharpness intact.

FAQ

Question: What makes this filter suitable for landscape photography?
Answer: The 15-stop density lets you extend exposure times for motion blur and atmospheric effects common in landscape work, while the high-definition glass and coatings preserve detail and colour.

Question: Will this filter change the colours in my images?
Answer: Neutral density filters are designed not to affect image coloration. This NiSi filter adds an infrared protection coating and double-sided Nano Coating to minimize colour shifts and maintain natural, vibrant colours.

Question: Is the filter made of glass or resin?
Answer: The filter is made from high-definition optical glass (H-K9L), not resin, which supports high resolution and detail retention.

Question: How does the IR coating help my photos?
Answer: The IR coating reduces infrared light passing through the filter. That prevents the unwanted red cast that can appear at small apertures and helps restore natural colours in long-exposure shots.

Question: What surface protection does the filter have?
Answer: The filter features Nano Coating on both sides that repels water and oil and reduces reflections, aiding durability and image quality.
