NiSi Square Nano IR GND Soft 100x150mm GND4 0.6

NiSi Nano IR Soft Graduated Neutral Density Filter

The NiSi Nano IR Soft Graduated Neutral Density (GND) filter is specially designed for landscape photographers. It is made from high-quality optical glass (H-K9L) with nano coating on both sides to preserve detail and prevent color cast, ensuring true-to-life colors and cleaner blacks.

Filter Design and Functionality

The filter features a soft graduated transition from a dense dark area at the top to clear at the bottom, allowing balanced exposure between bright skies and darker foregrounds. This soft-edge design is ideal when the transition between light and dark areas in the scene is not sharply defined, such as in mountainous landscapes.

The filter can be repositioned within the holder to recompose the image for optimal results.

Infrared Protection

Neutral density filters can be susceptible to infrared light, which may cause unwanted red color casts when shooting at small apertures. NiSi has applied an infrared protection coating layer to this filter to eliminate infrared light transmission through the lens, restoring natural color fidelity.
