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 can filter the sky while minimizing its effect on the land. It is particularly useful for images that include elements like rooftops and mountains that protrude into the sky. 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. \u003cbr\u003e \u003cbr\u003e The design of this filter has been optimized for use with digital sensors and to promote nearly flat attenuation of visible and infrared light. Due to imaging sensors' greater susceptibility to infrared light compared to traditional film, color casts can occur when photographing darker subjects that require increased exposure times. To provide neutrality across the visible and infrared spectrums in order to eliminate color casts and ensure cleaner, truer blacks, one layer of NiSi Optical Nano Coating is applied to each of this filter's surfaces. The Nano coating associated with this filter also results in an improved beading effect when in contact with water or oil for greater cleaning efficiency. \u003cbr\u003e \u003cbr\u003e This NiSi 150 x 170mm Nano Medium-Edge Graduated IRND 0.9 Filter is constructed from optical glass for clarity as well as color fidelity, and measures 2mm thick. \u003c\/p\u003e \u003c\/div\u003e \u003c\/div\u003e \u003cdiv\u003e \u003cdl\u003e \u003cdd\u003e150 x 170mm graduated neutral density filter darkens bright areas of an image, such as skies, while leaving the remainder of the frame unaffected.\u003c\/dd\u003e \u003c\/dl\u003e \u003cdl\u003e \u003cdd\u003e8x filter factor provides up to a 3-stop reduction of light in selective areas.\u003c\/dd\u003e \u003c\/dl\u003e \u003cdl\u003e \u003cdd\u003eMedium-edged line of transition between the dense and clear areas.\u003c\/dd\u003e \u003c\/dl\u003e \u003cdl\u003e \u003cdd\u003eUseful for images that include elements like rooftops and mountains that protrude into the sky.\u003c\/dd\u003e \u003c\/dl\u003e \u003cdl\u003e \u003cdd\u003eFilter does not affect coloration of the image and is ideal for use with other filters.\u003c\/dd\u003e \u003c\/dl\u003e \u003cdl\u003e \u003cdd\u003eEach 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.\u003c\/dd\u003e \u003c\/dl\u003e \u003cdl\u003e \u003cdd\u003eNano coating provides an improved beading effect with water or oil for more efficient cleaning.\u003c\/dd\u003e \u003c\/dl\u003e \u003cdl\u003e \u003cdd\u003eConstructed from optical glass for clarity.\u003c\/dd\u003e \u003c\/dl\u003e \u003cdl\u003e \u003cdd\u003eLeatherette pouch included for storage and transport.\u003c\/dd\u003e \u003c\/dl\u003e \u003c\/div\u003e \u003c\/div\u003e \u003c\/div\u003e\u003cdiv\u003e \u003cdiv\u003e \u003cdiv\u003e \u003cdiv\u003e \u003ctable\u003e \u003ctbody\u003e \u003ctr\u003e \u003ctd\u003eFilter Type\u003c\/td\u003e \u003ctd\u003eGraduated ND Combination\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eCombination Type\u003c\/td\u003e \u003ctd\u003eIR Attenuation\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eGraduation Type\u003c\/td\u003e \u003ctd\u003eMedium Edge\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eDensity\u003c\/td\u003e \u003ctd\u003e0.9 (3 Stops)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eShape\u003c\/td\u003e \u003ctd\u003eRectangle\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eRectangular Size\u003c\/td\u003e \u003ctd\u003e5.91 x 6.69\" \/ 150.0 x 170.0 mm\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eFilter Thickness\u003c\/td\u003e \u003ctd\u003e0.08\" \/ 2 mm\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eFilter Material\u003c\/td\u003e \u003ctd\u003eGlass\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eCoatings\u003c\/td\u003e \u003ctd\u003eResistance Coating\u003c\/td\u003e \u003c\/tr\u003e \u003c\/tbody\u003e \u003c\/table\u003e \u003ctable\u003e \u003ctbody\u003e \u003ctr\u003e \u003cth\u003e \u003ca\u003ePackaging Info\u003c\/a\u003e  \u003c\/th\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003ePackage Weight\u003c\/td\u003e \u003ctd\u003e0.7 lb\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eBox Dimensions (LxWxH)\u003c\/td\u003e \u003ctd\u003e9.0 x 8.5 x 0.75\"\u003c\/td\u003e \u003c\/tr\u003e \u003c\/tbody\u003e \u003c\/table\u003e \u003c\/div\u003e \u003c\/div\u003e \u003cdiv\u003e\u003c\/div\u003e \u003c\/div\u003e \u003c\/div\u003e \u003cdiv\u003e \u003cdiv\u003eIn the Box\u003c\/div\u003e \u003cdiv\u003e \u003cdiv\u003e \u003cdiv\u003eNiSi 150 x 170mm Nano Medium-Edge Graduated IRND 0.9 Filter (3 Stops)\u003c\/div\u003e \u003c\/div\u003e \u003cul\u003e \u003cli\u003eFilter Pouch\u003c\/li\u003e \u003cli\u003eLimited 1-Year Warranty\u003c\/li\u003e \u003c\/ul\u003e \u003c\/div\u003e \u003c\/div\u003e \u003cbr\u003eAll product and company names are trademarks™ or registered® trademarks of their respective holders.
