Cokin Z663 O2 - Graduated Fluorescent Orange Filter - Hard Edge, 1 1/3-Stop, "Z"

The Cokin Hard-Edge Graduated Fluorescent Orange 2 is a 1 2/3-stop filter that can be used to enhance dull, flat, or hazy skies. The filter is densest at the edge and graduates to clear at the middle, with a hard-edged line of transition. Hard-edge filters are great for images with a defined horizon line. The filter is rectangle so you can selectively choose where the orange edge sits in the framing of the image.
