Cokin A664 R1 - Graduated Fluorescent Red Filter - Hard Edge, 1 1/3-Stop, "A"

The Cokin Hard-Edge Graduated Fluorescent Red 1 filter 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 red edge sits in the framing of the image.
