The Tiffen 4x5.65" Pro-Mist F/X 1 glass filter is a soft focus filter. The Pro-Mist filter is exceptional for creating a special mood. Outdoors or indoors, in broad scenics or portraits, the Pro-Mist is excellent for toning down excessive sharpness and reducing contract by moderately lightening shadow areas without detracting from the overall image.
This is especially useful given the contrast and extremely sharp resolution produced by contemporary film and video lenses. Pro-Mist filters give your portraits that extra edge of professionalism. The various grades allow you to soften contrast to whatever degree you feel your subject requires.
