NiSi NIP-180-ND3.0 180x180mm IR ND1000 10-Stop Filter

The NiSi ND1000 180x180mm IR neutral density filter is designed for photographers who require extreme light reduction in a format large enough to cover ultra-wide-angle lenses. With a 10-stop (ND 3.0) density, this filter reduces light transmission to just 0.1%, enabling shutter speeds measured in seconds or minutes even under bright midday sun. This opens up creative possibilities that are impossible without filtration — smoothing ocean waves into mist, turning busy waterfalls into silk, and transforming scattered clouds into dramatic streaks of motion across the sky.

What sets this filter apart from budget alternatives is NiSi's nano IR coating technology. Standard ND filters can allow infrared light to pass through, producing reddish or magenta color casts that become increasingly pronounced at longer exposures. The IR coating on this filter blocks that contamination, maintaining more accurate color rendition straight out of camera. The same coating also repels water and oil, which is a practical advantage when shooting near waterfalls or coastlines. At 180x180mm, this filter is specifically sized for NiSi's large-format holder system, which fits lenses too wide for the more common 100mm filter setup. It is a professional-grade tool priced accordingly, and it requires the matching holder system to use.
