Kase 100 x 150mm Wolverine Hard-Edge Graduated ND 0.9 Filter (3-Stop)

Kase 100 x 150mm Wolverine Hard-Edge Graduated ND 0.9 Filter (3-Stop)
This Kase 100 x 150mm Wolverine Hard-Edge Graduated ND 0.9 Filter is compatible with a Kase 100mm Filter Holder or other filter holders that can accommodate 100mm wide, 2mm thick filters. It 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 hard-edged line of transition between the dense and clear areas. A neutral density filter with a hard-edged line of transition is particularly useful for images that feature horizons or any hard transition between the sky and land. 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 a lens.



Kase Wolverine filters are constructed from tempered, optical glass for shock resistance. To prevent internal ghosting and reflections, while further enhancing clarity and color fidelity, each glass surface includes multiple layers of anti-reflection coatings. These coatings also offer greater protection to the filter substrate and help it to stay clean for longer than with uncoated filters.
