Haida Drop-In Soft-Edge Graduated ND Filter for Haida M10 Filter Holder (4-Stop)

This 4-stop Haida Drop-In Soft-Edge Graduated ND Filter for Haida M10 Filter Holder 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 4-stop reduction in light from entering the lens. Mounted within a geared filter ring assembly, this filter is made specifically to fit between a separately available Haida M10 Filter Holder and an adapter ring for the filter holder. The geared filter ring assembly's external dial allows for the independent rotation of this graduated neutral density filter in order to allow for precise gradation positioning along the horizon line.
