The Tiffen 77mm Pearlescent 1/2 Filter can be applied to purposely soften contrast and reduce sharpness. This can be useful for high-resolution digital cinematography in order to create a more flattering result of a subject by reducing the appearance of blemishes and softening highlights. Additionally, a pearlescent halo around highlights is created which can further enhance a subject's appearance or produce a desired effect. This filter has a grade of 1/2. Grades of 1/8, 1/4, 1, and 2 are also available where this filter type's effect becomes approximately twice as strong with each grade number increase. This filter is 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.
