Meeting the requirements of directors of photography, Tiffen's new Black Glimmerglass® filters help filmmakers soften the sharp, 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 reduce the excessive sharpness of modern lenses, adding a pleasing blend to contrast levels. Furthermore, these filters maintain an overall sharp and clear image, providing a cinematic aura to digital acquisition.
