Responding to the demands of directors of photography, Tiffen's new Black Glimmerglass® filters help cinematographers soften the hard, precise edges of images produced by modern digital lenses and cameras, particularly with 4K sensors, and are designed to enhance the natural beauty of the shot with minimal signs of filtration.nnBlack Glimmerglass filters offer all the benefits of the original Glimmerglass filters, PLUS, they subtly remove excessive sharpness from modern lenses, adding a pleasant overall blend to contrast levels. Furthermore, these filters maintain an overall sharp and clear image, offering a cinematic aura to digital acquisition.
