The Freewell 72mm Magnetic Quick-Swap Soft-Edge Graduated Neutral Density 0.9 Filter 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. An included Freewell 72mm UV Filter allows the graduated neutral density filter to be used on a lens with 72mm front filter threads. Each surface of the Freewell 72mm Magnetic Quick-Swap Soft-Edge Graduated Neutral Density 0.9 Filter and the Freewell 72mm UV Filter is multi-coated to help eliminate internal ghosting and reflections. The Freewell 72mm Magnetic Quick-Swap Soft-Edge Graduated Neutral Density 0.9 Filter and the Freewell 72mm UV Filter are also coated for resistance to oil dust and scratches offering greater protection to the filters and helping them to stay clean for longer than with uncoated filters. The coatings are also hydrophobic resulting in an improved beading effect when in contact with water for greater cleaning efficiency. The Freewell 72mm Magnetic Quick-Swap Soft-Edge Graduated Neutral Density 0.9 Filter also includes 72mm front threads permitting the use of screw-on filters with 72mm rear threads.
