The Nisi 180x210mm 3 Stop Reverse Graduated Neutral Density Filter is specially designed for landscape photographers. This filter measures 180 x 210mm and is compatible with the Nisi 180mm filter holders. The filter can be repositioned in the holder allowing you to get the best result. The Nisi Reverse Graduated Neutral Density Filter is designed with 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.
