NiSi 150x170mm Nano IR Medium Graduated Neutral Density Filter - ND8 (0.9) - 3 Stop

The 150x170mm Nano IR Medium Graduated Neutral Density Filter - ND8 (0.9) - 3 Stop 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 medium-edged line of transition between the dense and clear areas. A neutral density filter with a medium-edged line of transition is particularly useful for images that feature buildings, small mountains and other elements that protrude into high into the skyline. The transition zone of a medium is 40% smaller than a Soft GND and is wonderful for shooting at sunrise and sunset.
