The 77mm MCS Glimmerglass Grade 1/2 Filter from Tiffen is a diffusion filter for portrait and beauty shots that 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 1/2 diffusion provides a very small amount of softening and overall image alteration. It provides a more cinematic look to stills and video when using digital cameras. This glass filter features a sparkling appearance when viewed from the front, which models may find appealing.
