NiSi Square Nano IRND 180x180mm ND64 6Stops

NiSi Square Nano IRND 180x180mm ND64 (6 Stops) – Nano Coated IR Neutral Density for True-to-Life Colors

This NiSi Square Nano IRND filter reduces light by 6 stops (ND64) and helps you shoot longer exposures while preserving natural color. It uses high definition optical glass and features nano coatings to manage reflections, repel water and oil, and reduce infrared contamination that can cause unwanted red casts.

Designed Use and Benefits

Photographers who capture landscapes will find this filter suited to long exposures and motion effects. By reducing the amount of visible light entering the lens, the filter enables slower shutter speeds for creative blur in water, clouds, or busy scenes. At the same time, the IR protection layer helps preserve accurate color reproduction when you shoot at small apertures.

How It Works

The filter uses neutral density to block visible light without changing the overall coloration of the image. However, standard ND filters can allow infrared light through, which may introduce a red cast in certain conditions. NiSi addresses this by adding an infrared protection coating to the filter, which reduces infrared transmission and helps return natural colors in your photographs.

Smart FAQ

Question: Will this ND filter change the color balance of my images?
Answer: The NiSi Nano IRND is a neutral density filter and does not intentionally change the coloration of the image. In addition, it includes an infrared protection coating to reduce infrared-induced color shifts, helping maintain true-to-life colors even at small apertures.

Question: Is this filter suitable for landscape long-exposure work?
Answer: Yes. The filter reduces visible light by 6 stops to allow slower shutter speeds, which is useful for smoothing water, blurring clouds, and creating motion effects in landscape scenes.

Question: How does the nano coating help in the field?
Answer: The nano coating is applied to both sides of the glass. It lowers reflections and helps repel water and oil, making it easier to keep the filter clean during outdoor shoots and reducing the need for frequent wiping.

Question: Are other density options available in the same size?
Answer: Yes. Apart from the 6-stop (ND64) version, NiSi offers the 180x180mm Nano IRND in 3-stop and 10-stop densities, giving you options for different exposure control needs.
