CLR/BLUE 3 Hard Edge Grad MPTV Camera Filter

The Tiffen Blue Hard Edge Graduated Filter is a Hard-edged graduated color filter providing a bluish color across the image, giving a cooling effect for your photographs. The 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. 

Tiffen filters are 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.
