Meeting the demands of directors of photography, Tiffen's new Black Glimmerglass® filters help filmmakers soften the sharp and hard 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. Black Glimmerglass filters offer all the benefits of the original Glimmerglass filters, PLUS they subtly eliminate the excessive sharpness of modern lenses, adding a pleasant overall blend to contrast levels. Furthermore, these filters maintain an overall sharp and clear image, providing a cinematic aura to digital acquisition.
