The Tiffen 6.6" CC20Y Yellow Filteris 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 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 and grinding flat to a tolerance of 1/10,000th of an inch. This filter measures 6.6 x 6.6" / 167.6 x 167.6mm.

Q: 10. What's the differences between Black Glimmerglass and Black Promist?

A: The glimmer glass filter is designed to take the crisp edges off the images that modern lenses and digital cameras produce. The filter subtly softens the image and lowers detail resolution for those who want to simulate the look of film footage while shooting on digital gear. This black Glimmerglass model reduces contrast and overall sharpness and can smooth out unwanted blemishes, wrinkles, or other fine details in a subject's face while keeping the general image in focus. The black pro mist filter helps to reduce the value of the highlights while slightly lowering the overall contrast. This filter is especially useful for smoothing out and softening facial wrinkles and other blemishes. While designed for use with movies, this filter can also be used for fashion and beauty applications. Unlike a traditional diffusion or soft focus filter, Pro-Mist filters provide little loss of detail across the image. The 1/8 density provides less contrast and highlight reduction than the 1/4, while still allowing for a soft, pastel-like quality of light.
