The Tiffen 4x5" Twilight Graduated Filterhelps to specifically add a unique deep magenta to pink gradient 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 2 color density provides less twilight coloration than the 3 density, but more than the 1 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.

2 Density Color Graduated Filter    Twilight Coloring in Select Areas    Soft-Step Graduation    ColorCore Technology

Provides a unique deep reddish magenta to pink gradient across half of the filter plane.

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.

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