Ice Hard-Edge Graduated ND Filter (100 x 150mm, 3-Stop)

This 3-stop, 100 x 150mm Ice Hard-Edge Graduated ND Filter is compatible with filter holders that can accommodate filters that are 100mm wide and 2mm thick. 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 the density provides up to a 3-stop reduction in light from entering the lens.
