Render difficult landscapes with natural tonality by using the Edge Hard-Edge Gradual Filter from IRIX, a three-stop neutral density filter that reduces the amount of light in a specific area of the frame to create the proper exposure for the entirety of the frame. The hard filter has a narrow transition between full transparency and maximum density and is useful for scenes where the horizon is flat and regular, such as the sea or an open field. The filter's optical glass features multi-layer, anti-reflective coating and comes in a protective case for storage and transport.
