Urth's 75 x 100mm Soft Graduated ND16 (4 Stop) Filter Plus+ is a rectangular filter that darkens specific parts of a photo, such as bright skies, while leaving the rest of the image area normally exposed. The filter is densest at the edge and tapers toward clear in the center, with a soft transition line between the dense and bright areas. This soft-edged design is suitable for photos with a prominent horizon or a soft transition between sky and land, such as forested landscapes and cityscapes. This filter reduces the light entering the lens by 4 stops and does not affect the color of the image.
