NiSi Square Nano IR GND Reverse 100x150mm GND 0.9

NiSi Square Nano IR GND Reverse Filter

The NiSi Reverse Nano Infrared Graduated Neutral Density (GND) filter is specially designed for landscape photographers to manage challenging lighting conditions such as sunrises and sunsets. This filter is made from high-quality optical glass (H-K9L) with advanced nano coating on both sides to preserve image detail and prevent loss of sharpness.

Design and Functionality

The filter features a darkened area centered in the middle that gradually fades towards the top, while the bottom part remains completely clear. This design helps prevent overexposure of the skyline or horizon line, which is often brighter during sunrise or sunset. The filter can be slid within the holder to adjust the position of the graduated effect, allowing precise composition for optimal results.
