The Tiffen 4 Red Soft-Edge Graduated Filter 6.6"x6.6"helps to specifically add a warm, bright red 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 4 color density provides less red coloration than the 5 density, but more than the 3 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 6.6 x 6.6" / 167.6 x 167.6mm.

4 Density Color Graduated Filter    Red Coloring in Select Areas    Soft-Step Graduation    ColorCore Technology

Provides a bright red 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.
