The Tiffen 52mm Warm Pro-Mist 4 Filter helps to reduce the value of the highlights while noticeably 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 4 density provides a very noticeable amount of contrast and highlight reduction and allows for 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, grinding flat to a tolerance of 1/10,000th of an inch, and then mounting to precision metal rings.
