The Tiffen 4 x 4" 2 Straw Solid Color Filter adds a warm, golden yellowish coloration across the entire image and helps to subdue overly bluish casts. The solid color design makes this filter well-suited to pairing with other filters for further control over the appearance of imagery. The 2 color density provides less straw 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 4" / 101.6 x 101.6mm.
