The Tiffen 6 x 6" 1 Tropic Blue Soft-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 soft-edged transition between the density and clear areas. The 1 color density provides less tropic blue coloration 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 6 x 6" / 152.4 x 152.4mm.

1 Density Color Graduated Filter    Tropic Blue Coloring in Select Areas    Soft-Step Graduation    ColorCore Technology

Provides a deep greenish blue 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.
