The Tiffen 2 x 3" 4 Coral Hard-Edge Graduated Filter helps to specifically add a warm, pale orange 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 4 color density provides less coral 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 2 x 3" / 50.8 x 76.2mm.

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

Provides a natural-looking warming effect 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.
