The Tiffen Gold Diffusion/FX 2 4 x 4" Filter diffuses strong light entering the lens and produces a halation effect. Whilst the resulting image appears softer and more ethereal, there is little loss of sharpness or detail. This filter works by diffusing the light entering the lens with small aberrations; by distributing the light more evenly, a soft halo is created rather than the sharp, well-defined image obtained 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 2 offers more softening than 1, but less than 3. nnTiffen filters are manufactured using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass and polishing it flat to a tolerance of 1/10,000th of an inch. This filter measures 4 x 4" / 101.6 x 101.6 mm.nnnFeatures:nn- The diffusion filter gives photographs an ethereal quality, creating a dreamlike atmosphere.n- The soft image quality does not compromise the overall detail of the image.n- Light entering the lens is diffused by small aberrations, creating a soft halo rather than the sharp, well-defined image obtained without a filter.n- The golden tint brings additional warmth and helps to balance skin tones.nnnSpecifications:nn- Type: Gold Diffusern- Size: 4 x 4" / 101.6 x 101.6 mmn- Grade: Density 2n- Effect: Diffuses light entering the lens, creating a halation effect.
