The Tiffen Bronze Glimmerglass 2 4 x 5.65" Filter is a dual-function enhancement filter: in addition to modifying the appearance of the image itself, it also presents a sparkling appearance when viewed from the front, thus inspiring greater confidence in the subject. The filter itself imparts a bronze tint to the image and helps to soften skin detail and blemishes. It also produces luminous highlights and a slight reduction in contrast for a more ethereal look. Density 2 provides more bronze tint than 1, but less than 3. nnThis filter is 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 4 x 5.65" / 101.6 x 143.5 mm.nnn- The bronze tint brings additional warmth to the image and helps to soften skin detail and blemishes.n- Produces luminous highlights and a slight reduction in contrast for a more ethereal image appearance.n- Viewed from the subject's perspective, the filter appears to sparkle and helps to inspire confidence in subjects, which can translate into better performances.nnnSpecificationsnn
