NiSi Explorer Collection 150x170mm Nano IR Reverse Graduated Neutral Density Filter - GND4 (0.6) - 2 Stop

The NiSi Explorer Collection 150x170mm Reverse GND4 (2-Stop) is a graduated neutral density filter built specifically for shooting directly into a light source at the horizon, such as a sunrise or sunset over open water. Unlike a standard hard-edge GND, its darkest band sits right at the transition line and tapers outward, matching scenes where light is harshest at the horizon and falls off toward the sky. It suits seascapes and other compositions with a sudden foreground-to-sky transition and no elements breaking the horizon.

• 2-Stop Reverse Graduated ND: Darkest band sits at the transition point rather than at the filter's edge.
• Built for Shooting Into Light: Matches scenes where the horizon is brightest and light falls off toward the sky.
• Ideal for Open Horizons: Suited to seascapes and landscapes with no elements breaking the skyline.
• Hardened B270 Glass: Explorer Series glass hardening doubles strength versus typical glass filters.
• NiSi 150mm System Compatible: Fits directly into the existing NiSi 150mm filter holder system.
