The Tiffen 4 x 5.65" Bronze Glimmerglass 3 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 3 density provides more bronze tint that the 2, but less than the 4.
