The 4 x 5.65" Black Pro-Mist 1/4 Filter from Tiffen produces diffusion with less highlight and shadow effect than Tiffens standard Pro Mist filter. The Black Pro Mist is known for its soft, pastel approach to portraiture. Highlights do not blow out and there is less of an opening of the shadows while your images will appear brighter and more flattering to your subject. Contrast is reduced but you will not experience a significant glow or flare around your highlights. This filter is part of Tiffens Hollywood F/x series that was originally created for MPTV use. However, it can be applied to any photographic medium - still or video. The 1 Black Pro Mist is the first full step this filter is available in. The image looks even softer with the edge taken off any inherent sharpness of the equipment being used. A pleasing pearlescent glow appears around the highlights. Contrast continues to be minimized. Tiffens ColorCore glass is produced through a process that entails permanently laminating the filter material in between two pieces of optical glass that are ground flat to tolerances of a ten-thousandth of an inch, then mounting them in precision aluminum rings.
