The Black Pro-Mist offers all the benefits of the Pro-Mist filter in a more subtle form. Highlight flares are controlled. Contrast is lowered, but with less lightening of shadows for a more delicate effect. Tones down excessive sharpness to create the "film look".
Black Pro-Mists are useful when shooting exteriors for softening highlights and reducing contrast, though are also great on fashion and portrait projects for reducing the “digital” appearance of blemishes and wrinkles.
