Product Description

The NiSi Nano Soft-Edge Graduated IRND 100 x 150mm 3-Stop Filter is a professional rectangular GND filter designed to balance exposure in highcontrast scenes. With a soft transition from dark to clear, it is ideal for scenes where the horizon is uneven, such as mountains, trees, cities, or rolling landscapes.
