The Tiffen 4 x 5.65" Black Pro-Mist 1/4 Filter is designed to reduce highlight intensity and slightly lower overall contrast in a manner that retains image detail. Its primary purpose is to smooth and soften facial wrinkles and blemishes, making it beneficial for movies, fashion, and beauty applications alike. Unlike typical diffusion or soft focus filters, the Pro-Mist filter achieves a gentle, pastel-like quality of light without significant loss of image detail. Tiffen employs ColorCore technology, which involves laminating the filter substrate between two optical glass pieces ground to a precision of 1/10,000th of an inch. The filter size is 4 x 5.65" / 101.6 x 143.5mm.
