The Tiffen Soft/FX 1 5 x 5" 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 light more evenly, a soft glow is created rather than the sharp, well-defined image obtained when shooting without a filter. Density 1 provides more softening than 1/2, but less than 2. Tiffen filters are manufactured 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 5 x 5" / 127 x 127 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 obtained when shooting without a filter.
