The NiSi 100x150mm Nano Soft-Edge Graduated IRND 0.9 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 3-stop reduction in light from entering the lens
8x filter factor provides up to a 3-stop reduction of light in selective areas.
Soft-edged line of transition between the dense and clear areas.
Useful for images that do not have a strongly defined transition between the sky and the foreground.
Filter does not affect coloration of the image and is ideal for use with other filters.
Each surface includes one layer of NiSi Optical Nano Coating that attenuates infrared light as well as visible wavelengths, to maintain color neutrality and suppress color casts due to increased exposure times.
Nano coating provides an improved beading effect with water or oil for more efficient cleaning.
Constructed from optical glass for clarity.
Leatherette pouch included for storage and transport.
