The Tiffen 6.6 x 6.6" Gold Diffusion/FX 1 filter diffuses strong light entering the lens and produces a halo effect. While the resulting image appears softer and more ethereal, there is little loss of clarity or detail. This filter works by diffusing light entering the lens with small aberrations; by distributing light more evenly, a gentle halo 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, giving more warmth and helping to balance skin tones. The 1 density 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 to a tolerance of 1/10,000th of an inch. This filter measures 6.6 x 6.6" / 167.6 x 167.6mm.nnn- The diffusion filter brings an ethereal quality to photographs, resulting in a dreamlike atmosphere.n- The soft image quality does not detract from the overall detail of the image.n- Light entering the lens is diffused by small aberrations, creating a gentle halo rather than the sharp and well-defined image when shooting without a filter.n- The golden tint brings additional warmth and helps balance skin tones.nnnSpecificationsnn
