Cavision Graduated ND Glass Filter (100 x 150mm, 3-Stop)

This 3-stop, 100 x 150mm Cavision Graduated ND Glass Filter is a rectangular filter that 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 medium soft-edged line of transition between the dense and clear areas. A neutral density filter with a medium soft-edged line of transition is particularly useful for use with lenses that have a focal length up to 70mm (in 35mm format) when capturing images that do not have a strongly defined transition between the sky and the foreground. This filter fits in the Lee 100mm system filter holder, which allows you to adjust the position of the transition line, as well as the orientation of the filter.
