The Tiffen Black Diffusion/FX 1/4 4 x 5.65" filter diffuses strong light entering the lens and produces a luminous effect. Whilst the resulting image appears softer and more ethereal, there is little loss of clarity or detail. This filter works by diffusing the light entering the lens with small aberrations; by distributing the light more evenly, a soft glow is created rather than the sharp, well-defined image when shooting without a filter. The 1/4 density offers less softening than the 1/2.

Tiffen filters are manufactured using ColorCore technology, a process that involves laminating the filter substrate between 2 optical glass plates and polishing it flat to a tolerance of 1/10,000th of an inch. This filter measures 4 x 5.65" / 101.6 x 143.5 mm.


- The diffusion filter imparts an ethereal quality to photographs, creating a dreamlike atmosphere.
- The soft image quality does not compromise overall image detail.
- Light entering the lens is diffused by small aberrations, creating a soft glow rather than the sharp, well-defined image when shooting without a filter.
