The Tiffen Series 9 2 Tropic Blue Solid Color Filter adds a cool, aqueous coloration across the entire image and helps to subdue overly reddish 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 tropic blue 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, grinding flat to a tolerance of 1/10,000th of an inch, and then mounting to precision metal rings. It is compatible with Series 9 filter holders.
