The Tiffen 5 x 6" Warm Black Pro-Mist 4 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 Black Pro-Mist is similar to regular Pro-Mist, except that it will not lower contrast as much, thus keeping blacks more black. Preserves more detail in shadows, supresses halation more effectively, a bit more subtle for a more natural look especially in close-ups.
The 4 density provides more contrast and highlight reduction than the 3, but less than the 5, while still offering a soft, pastel-like quality of light.
This filter also combines the diffusion effect with an 812 warming filter for providing a general warmth to the image and for improving skin tones. This warming effect also helps to reduce blue sensitivity and for cutting through overly cool tones within the scene.
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.
