The Tiffen 4 x 5.65" Glimmerglass 1/2 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 helps to soften skin details, blemishes, and wrinkles. It also produces glowing highlights and a mild reduction in contrast for a more ethereal appearance. The 1/2 density provides more softening than the 1/4, but less than the 1.
