The Tiffen Pro-Mist 1 4 x 5.65" filter helps reduce highlight values whilst noticeably decreasing overall contrast. This filter is particularly useful for smoothing and softening facial wrinkles and other imperfections. Although designed for cinematographic use, this filter can also be used for fashion and beauty applications. Unlike a traditional diffusion or blur filter, Pro-Mist filters offer minimal loss of detail across the entire image. The density 1 offers more contrast and highlight reduction than the 1/2, but less than the 2, whilst allowing for a soft, pastel light quality. Tiffen filters are manufactured using ColorCore technology, a process which involves laminating the filter substrate between 2 pieces of optical glass and grinding it flat to a tolerance of 1/10,000th of an inch. This filter measures 4 x 5.65" / 101.6 x 143.5 mm. - Pro-Mist filters offer minimal loss of detail across the entire image compared to traditional diffusion and blur filters. - Particularly useful for smoothing and softening facial wrinkles and other imperfections. - Pro-Mist filters offer minimal loss of detail across the entire image compared to traditional diffusion and blur filters.
