The Tiffen 2 x 2" 3 Coral Solid Color Filter adds a warm, pale orange 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 3 color density provides less coral coloration than the 4 density, but more 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 2 x 2" / 50.8 x 50.8mm.
