The Tiffen 6.6 x 6.6" Black Diffusion/FX 1/4 filter diffuses strong light entering the lens and produces a luminous effect. Although 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 obtained when shooting without a filter. The 1/4 density provides less softening than the 1/2.

Tiffen filters are made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass and grinding it flat to a tolerance of 1/10,000th of an inch. This filter measures 6.6 x 6.6" / 167.6 x 167.6 mm.


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