This NiSi Square Nano IR GND Soft 150x170mm filter places a dark area at the top and transitions gradually to clear at the bottom. It prevents overexposure of skies while keeping the lower parts of the scene properly exposed. You can use it when the transition between bright and dark areas is not well defined, for example in mountainous terrain.
NiSi designed this filter specifically with landscape photographers in mind. It helps you control sky brightness without affecting foreground detail. Moreover, the filter can be repositioned in the holder, which allows you to recompose the photo and align the graduated transition where you need it most.
The filter is made from high quality optical glass (not resin). NiSi added a nano coating to preserve fine detail. In addition, the filter includes an infrared protection coating layer. This layer reduces infrared contamination that can cause a red color cast when shooting at small apertures, helping to restore natural colours in your images.
These NiSi Nano IR Soft Graduated Neutral Density filters in 150x170 mm are available in multiple strength options. Choose the stop reduction that fits your scene. The available options are:
