The 52mm Glimmerglass Grade 1 Filter from Tiffen 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 helps soften skin details, blemishes, and wrinkles. It also produces glowing highlights and a mild reduction in contrast for a more ethereal appearance. The grade 1 diffusion provides a small amount of softening and overall image alteration.
This filter is made using ColorCore technology, a process that involves laminating the filter substrate between two pieces of optical glass, grinding it flat to a tolerance of 1/10,000th of an inch, and then mounting it onto precision metal rings.
