The Tiffen 86mm Coarse Thread Bronze Glimmerglass 4 Filter is a beauty filter whose function is two-fold: in addition to modifying the appearance of the image itself, it also features a sparkling appearance when viewed from the front, instilling more confidence in the model. The filter itself imparts a bronze tint across the image and helps to soften skin details and blemishes. It also produces glowing highlights and a mild reduction in contrast for a more ethereal appearance. The 4 density provides a noticeable amount of bronze tint and overall image alteration.
This filter is made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass, grinding flat to a tolerance of 1/10,000th of an inch, and then mounting to precision metal rings.
