The Tiffen 4 x 5.65" Gold Diffusion/FX 1 filter diffuses strong light entering the lens and produces a luminous effect. nnWhilst the resulting image appears softer and more ethereal, there is little loss of clarity or detail. nnThis filter works by diffusing the light entering the lens with small aberrations; by distributing the light more evenly, a gentle glow is created rather than the sharp and well-defined image when shooting without a filter. In addition to the diffusion provided, a golden tint is also added to the image, bringing more warmth and helping to balance skin tones. Density 1 offers more softening than the 1/2, but less than the 2. nnTiffen filters are manufactured using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass and grinding it flat with a tolerance of 1/10,000th of an inch. This filter measures 4 x 5.65" / 101.6 x 143.5 mm.nnThe diffusion filter imparts an ethereal quality to photographs, resulting in a dreamlike atmosphere.nnThe soft image quality does not compromise the overall detail of the image.nnLight entering the lens is diffused by small aberrations, creating a gentle glow rather than the sharp and well-defined image when shooting without a filter.nnThe golden tint brings additional warmth and helps to balance skin tones.
