Tiffen Filters 4x4 Cool Blue 3 Filter - 44CB3
The Tiffen 4 x 4" 3 Chocolate Solid Color Filter adds a mellow, neutral brown coloration across the entire image and adds some warmth to balance overly cool tones. The solid color design makes this filter well-suited to pairing with other filters for further control over the appearance of imagery. The 3 color density provides more chocolate coloration than the 2 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 4" / 101.6 x 101.6mm.
