His weapon? The split neutral-density filter, a half-tinted piece of glass that makes the sky look as good as the ground. To get great landscapes, Adamus suggests that you start with the basics: three split neutral-density filters, including a 2-stop hard-edge, a 3-stop hard-edge, and a 3-stop soft-edge, also called a graduated; and, if you shoot large bodies of water, a polarizing filter to cut glare and reduce unwanted reflections. He does all his shooting digitally in RAW. And when filters aren't enough, or if the line of the graduated filter interrupts the landscape, he uses Photoshop to pick up where the filters left off.
