The Tiffen 2 x 2" CC50Y Yellow Filter is 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.

Yellow is the opposite of blue and can be used to reduce blue tones or casts within a scene or print. This yellow CC50 is more dense than a CC40 filter and less dense than a CC70 filter, and requires a 0.6 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 and grinding flat to a tolerance of 1/10,000th of an inch. This filter measures 2 x 2" / 50.8 x 50.8mm.
