The Tiffen 4 x 5" 5 Green Soft-Edge Graduated Filter helps to specifically add a bright green 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 5 color density provides more green coloration than the 4 density filter.
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. It measures 4 x 5" / 101.6 x 127mm.
Note: A horizontal orientation filter's line of transition runs parallel to the long side of the filter.
