The Tiffen 127mm 4 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 4 color density provides less coral coloration than the 5 density, but more than the 3 density filter.

This filter is made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass, grinding flat to a tolerance of 1/10,000th of an inch, and then mounting to precision metal rings.
