The Tiffen Series 9 CC20R Red Filter - Camera Accessoryis a color compensating (or color correction) filter for use when making color balance adjustments. It can be used to alter the color balance of a scene by placing in front of a light source or the lens of your camera. It can also be used to apply color corrections when used in the darkroom with an enlarger or to help pre-visualize color adjustments when viewing prints.

Red is the opposite of cyan and can be used to reduce cyan tones or casts within a scene or print. This red CC20 is more dense than a CC10 filter and less dense than a CC30 filter, and requires a 0.3 stop compensation for normal exposure results.

Tiffen filters are 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, then mounting to precision metal rings. This filter is compatible with Series 9 filter holders.
