NiSi Nano Soft-Edge Graduated IRND Filter (150 x 170mm, 5-Stop)

This 5-stop, 150 x 170mm NiSi Nano Soft-Edge Graduated IRND Filter is a rectangular filter that helps to darken specific areas of an image, such as bright skies, while allowing for a normal, unaffected exposure in the other regions of the image. The filter is densest at the edge and tapers to clear by the middle, with a soft-edged line of transition between the dense and clear areas. A neutral density filter with a soft-edged line of transition is particularly useful for images that do not have a strongly defined transition between the sky and the foreground. Neutral density filters do not affect the coloration of the image and this filter provides up to a 5-stop reduction in light from entering the lens.
