The Tiffen Glimmerglass 1 Round 4.5" Filter is an enhancement filter with a dual function: in addition to modifying the appearance of the image itself, it also presents a sparkling appearance when viewed from the front, which inspires greater confidence in the model. The filter itself helps soften skin detail, imperfections and wrinkles. It also produces luminous highlights and a slight reduction in contrast for a more ethereal look. Density 1 offers a small amount of softening and overall image modification. nnThis filter is manufactured using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass, polishing it flat to a tolerance of 1/10,000th of an inch, and then mounting it on precision metal rings.nnnFeatures:nn- Produces luminous highlights and a slight reduction in contrast for a more ethereal image appearance.n- Helps soften skin detail, imperfections and wrinkles.n- Viewed from the subject's perspective, the filter appears to sparkle and helps inspire confidence in models, which can result in better performance.nnnSpecifications:nn- Type: Softening Filtern- Size: 4.5" / 114.3 mm (diameter)n- Grade: Density 1n- Effect: Produces luminous highlights and softens skin detailn- Construction: ColorCore Technologyn- Front Filter Thread Size: 4.5" / 114.3 mm (diameter)n- Front Lens Cap Size: 4.5" / 114.3 mm (diameter)
