Tiffen diffusion filter that softens shadows and adds a subtle glow without color shift.
Technical Details
White Pro-Mist is available in strengths of 1/8, 1/4, 1/2, 1, 2, 3, 4, and 5, with 1/4 and 1/2 being the most commonly used. Light loss is approximately 1/3 to 2/3 of a stop depending on the filter grade. The filter reduces contrast by 10-15% at grade 1/4 and up to 40% at grade 2. Standard thread sizes range from 52mm to 138mm, with professional matte box versions available as 4"×4" or 4"×5.65" slices. Spectral transmission is evenly distributed across the visible spectrum, resulting in no color shift.
History & Development
Tiffen developed the Pro-Mist filter in 1978 in response to the increasing sharpness of modern lenses, which amplified skin imperfections and harsh shadows. White Pro-Mist established itself as a standard in commercial and portrait photography in the 1980s before transitioning massively into film production. With the advent of digital cameras from 2000 onwards, the filter gained new significance as digital sensors often produce overly sterile, high-contrast images. Modern versions utilize improved coatings with higher durability and reduced tendency for reflections.
Practical Use in Film
Cinematographer Emmanuel Lubezki systematically used White Pro-Mist 1/4 in "The Revenant" (2015) for more natural skin tones with available light. In "Her" (2013), Hoyte van Hoytema combined various Pro-Mist grades with warm lighting for the characteristic soft image aesthetic. The filter is particularly suitable for close-ups and medium shots, as it disguises skin imperfections without eliminating detail. In night shots, Pro-Mist enhances the halo effect of light sources and creates atmospheric scattered light. Caution is advised with strong backlight, as the filter can increase flares and ghosting.
Comparison & Alternatives
Unlike Black Pro-Mist, White Pro-Mist maintains original color saturation and does not create shadow lifting. Glimmer glass produces similar effects but diffuses less evenly and is harder to control. Digital alternatives such as DaVinci Resolve's "Film Halation" or ARRI's "Amira Look Files" simulate the effect but do not achieve the optical quality of the physical filter. Schneider-Kreuznach's Hollywood Black Magic filter offers comparable performance at a higher price. For extreme budget constraints, a UV filter treated with hairspray can serve as a makeshift solution, albeit with unpredictable results.
