NiSi 100x100mm Nano IR Neutral Density filter – ND64 (1.8) – 6 Stop

Description

Overview

The NiSi 100x100mm Nano IR Neutral Density Filter – ND64 (1.8) – 6 Stop is a square optical glass ND filter designed for photographers working with the NiSi 100mm square filter system. At 6 stops of light reduction, this filter gives landscape photographers, seascape shooters, and long exposure enthusiasts precise control over exposure in a wide range of lighting conditions, from bright midday sun to the softer light of golden hour.

This filter is built for use with the NiSi 100mm filter holder and is compatible with lenses using standard filter threads from 49mm to 95mm via the appropriate adapter ring. It is a practical, field-ready solution for anyone who wants to extend shutter speeds, manage bright ambient light, or introduce deliberate motion blur into their images.

Experience & Benefits

The ND64 designation represents a 6-stop reduction in light, which translates directly into creative flexibility in the field. By reducing the amount of light entering your lens, this filter allows you to shoot at slower shutter speeds without overexposing your image. This makes it particularly effective for long exposure photography, where the goal is to render moving water as smooth silk, blur the motion of clouds across a wide sky, or extend exposures during bright daylight conditions where even a small aperture would not be sufficient on its own.

One of the most common challenges with neutral density filters is unwanted color shift. NiSi addresses this directly through an infrared protection coating layer built into the filter’s construction. This coating prevents infrared light from passing through the glass and introducing a reddish cast into the image. The result is more accurate, natural color reproduction across a wide range of shooting situations, which is especially important for landscape and seascape photographers who rely on consistent tones and true-to-life colors in their images.

The filter is constructed from high-quality optical glass and treated with a nano coating that minimizes surface reflections. Reduced reflections contribute directly to image clarity by limiting the internal light scatter that can soften fine detail or introduce unwanted artifacts. This attention to optical construction means that the filter performs reliably whether you are shooting raw files for post-processing or capturing images that need minimal correction straight from the camera.

For landscape photography filters used in the field, low color cast performance is a meaningful differentiator. When stacking this ND filter with a circular polarizer or a graduated ND, maintaining neutral color across all elements of the filter stack helps preserve accurate color in the final image without requiring excessive correction in post. The Nano IR ND64 is well suited to this kind of stacked workflow within the NiSi 100mm system.

The 6-stop reduction is a widely used strength for general long exposure work. In bright conditions, it provides enough light reduction to allow exposures of several seconds, making it a practical choice for photographing waterfalls, coastal seascapes, or urban scenes where movement adds context and atmosphere to the image. It also works well during golden hour, when the available light is lower and longer exposures become achievable with a filter of this strength.

Practical Details

The 100x100mm format is designed specifically for the NiSi 100mm filter holder system, which supports lenses with standard filter threads ranging from 49mm to 95mm using the appropriate adapter ring. If you are already working with the NiSi 100mm system, this filter slides directly into the holder alongside other square or rectangular filters in your kit, allowing you to combine ND filtration with graduated ND or other effects without removing and reattaching individual elements.

For photographers who are building or expanding a square filter system, the 100x100mm ND64 is a logical starting point or a key addition to an existing kit. The NiSi 100mm system is compatible with a broad range of lenses and camera platforms, making it one of the most versatile square filter system formats available. Once you have the holder and a selection of adapter rings for your lenses, adding filters of different strengths is straightforward and cost-effective over time.

Handling square optical glass filters in the field requires care, and the 100x100mm size is practical for travel and outdoor use without being overly large or cumbersome. The filter’s size, combined with the structured NiSi 100mm holder system, keeps setup time manageable, which is important when light is changing quickly and you need to move efficiently between compositions.
