The Tiffen 4 x 6" 3 Cyan Hard-Edge Graduated Filter helps to specifically add a bright cyan 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 3 color density provides less cyan coloration than the 4 density, but more than the 2 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 6" / 101.6 x 152.4mm.

Note: A vertical orientation filter's line of transition runs parallel to the short side of the filter.

3 Density Color Graduated Filter    Cyan Coloring in Select Areas    Hard-Step Graduation    ColorCore Technology

Provides a bright cyan coloring to select areas of the image.

Graduated filter design keeps a portion of the image neutral, resulting in a more realistic look while allowing for the sky or other bright areas to take on the color of the density.
