For Extreme Light Control in High-Contrast Scenes

Take full control of extreme brightness differences in your landscape photography with the KANI Premium Hard GND 3.9 filter. Designed for professionals who demand top-tier optical quality and cinematic precision, this 100×150mm rectangular GND filter delivers unparalleled results in high-dynamic-range environments.

Hard Edge, Ultra-Strong Gradation

Unlike standard GNDs, this filter features a Hard Gradation where the ND effect is most intense at the top and transitions sharply to the middle. With an ND10000 strength (equivalent to 13 stops), it’s ideal for taming intense highlights such as:

• Mountain peaks lit by the sun

• Reflective snow scenes

• Harsh backlit skies

KANI’s proprietary design maintains a smooth gradient in the middle zone, avoiding the harsh cutoff found in traditional hard GNDs.
