NiSi 100x150mm Reverse Nano IR Graduated Neutral Density Filter – ND4 (0.6) – 2 Stop

The NiSi 100x150mm Reverse Nano IR Graduated Neutral Density Filter is a professional-grade rectangular filter designed for landscape and outdoor photography. Featuring a reverse gradient design that darkens from the centre outward, this filter helps control overexposure in bright skies during sunrise and sunset whilst maintaining natural exposure in the foreground. Crafted from high-quality optical glass with NiSi Nano Coating technology on both sides, it delivers superior light transmittance and features infrared protection coating to eliminate unwanted colour casts when shooting at small apertures. The hard-edged transition makes it ideal for scenes with distinct sky-to-horizon lines, such as seascapes and level landscape vistas.
