The Nisi 150x170mm Reverse Graduated Neutral Density Filter is specially designed for landscape photographers. This filter measures 150 x 170mm and is compatible with the Nisi 150mm filter holders as well as any other standard 2mm thick holder. The filter can be repositioned in the holder allowing you to get the best result. The Nisi Reverse Neutral Density Filter is designed with the darkest area on the center of the filter and gradually lighter to the top while the bottom part is clear. It is perfect for sunrises and sunsets, or any other situation where your horizon is the brightest part of your image.
Like the rest of the NiSi line, this filter is made of high quality, precision annealed, optical glass. Its surface is finely ground and polished to ensure sharpness for today’s ultra-high megapixel cameras.
The NiSi Reverse Graduated Neutral Density Filter features NiSi’s unique NANO Coating technology. This multi-layer coating reduces reflection on the surface of the filter to help with ghosting and flare. It also includes a protective layer that makes it easy to wipe off water, dust, and oil from the filter without worrying about scratching your glass. The NANO Coating process achieves this without a color shift or loss in sharpness.
