NiSi Square Nano IR GND Soft 150x170mm GND4 0.6

NiSi Square Nano IR GND Soft Graduated Neutral Density Filter 150x170mm

The NiSi Nano IR Soft Graduated Neutral Density (GND) filter is specially designed for landscape photographers. It is constructed from high-quality optical glass (H-K9L) with nano coating on both sides to preserve detail and prevent loss of image quality.

This filter features a soft graduated transition from a dense dark area at the top to clear at the bottom, allowing balanced exposure of bright skies and darker foregrounds. The soft edge design is ideal when the transition between bright and dark areas is gradual, such as in mountainous landscapes.

Neutral density filters do not affect the coloration of the image, and this filter includes an infrared protection coating to eliminate unwanted infrared light that can cause red color casts when shooting at small apertures. The filter can be repositioned within the holder to recompose the image for optimal results.
