NiSi Explorer Collection 150x170mm Nano IR Medium Graduated Neutral Density Filter - GND8 (0.9) - 3 Stop

The NiSi Explorer Collection 150x170mm Medium GND8 (3-Stop) is a graduated neutral density filter built for photographers shooting scenes where buildings, mountains, or other elements break the horizon line. Its medium-edged transition zone — 40% narrower than a Soft GND — darkens bright skies while keeping the rest of the frame at a normal, unaffected exposure, making it well suited to sunrise and sunset shooting. Explorer Series filters use a special glass hardening process that doubles the strength of typical glass filters, so it's built to withstand the bumps of active outdoor photography.
