Tiffen 2 x 2" 1 Tropic Blue Hard-Edge Graduated Filter

The Tiffen 2 x 2" 1 Tropic Blue Hard-Edge Graduated Filter helps to specifically add a cool, greenish-blue coloration to skies and other bright areas of an image while allowing a portion of the image to remain neutrally colored. The filter's coloring is densest at the edge and tapers to clear by the middle, with a hard-edged transition between the density and clear areas. The 1 color density provides less tropic blue coloration than the 2 density filter.
