Description
The Tiffen 6.6×6.6″ Cool Blue Hard-Edge Graduated Filters helps to specifically add a cool, purplish-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 hard-edged transition between the density and clear areas.
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.
Note: A vertical orientation filter’s line of transition runs parallel to the short side of the filter.
- Provides a deep cool 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.
