The Nisi 180x210mm Nano IR HardåÊGraduated Neutral Density Filter – ND8 (0.9) – 3 Stop is specially designed for landscape photographers. This filter is made from high quality optical glass (not rasin) with nano coating to prevent losing any single bit of detail. Sunset and sunrise photography sometime can be the challenge. åÊNeutral density filters do not affect the coloration of the image and the 0.9 density provides a 3 stop reduction in light from entering the lens.åÊThis filter measures 180 x 210mm and is compatible with the Nisi 180mm filter holder for Canon 11-24mm. The filter can be repositioned in the holder allowing recompose the photo for the best result.
Hard grad filters are commonly used to control the exposure on even horizons andåÊwhen the horizon is level oråÊunbroken such as coast lines.
By using neutral density filter the camera isåÊvulnerable to infrared light which will cast the unwanted red color to the photos when shotting at small aperture. Nisi added the infrared protection coating layer to this filter which help to eliminate the infrared light through the lens to bring back the nature color.
