Tiffen GRAD CLR/Tropic Blue 3 SE
The Tiffen GRAD CLR/Tropic Blue 3 SE 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 soft-edged transition between the density and clear areas. The 3 color density provides more tropic blue coloration than the 2 density.
This filter is made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass and grinding flat to a tolerance of 1/10,000th of an inch. ADD ITEM
