HD video is very high contrast than traditional film. The HDTV/FX filter takes the edge off undesired ?tack sharpness? associated with HD. It creates a ?Film Look? by reducing contrast and also provides subtle improvements in shadow detail. The HDTV/FX filter smoothes out unwanted detail and makes people look their best, especially when shot on HD without evidence of filtration. Made of the highest quality optical glass, HDTV/FX filters combine Tiffen?s award-winning Ultra Contrast Filter with the new Digital Diffusion/FX filter. Although results may be very subtle with still photography, the effects of the HDTV/FX are seen more substantially with digital and video applications. HDTV/FX filters are available in ¼, ½, 1, 2, 3, 4 and 5 densities for more effect. i Tiffen filters are backed by a 10-year warranty. They are used in almost every major movie and TV production around the world. Tiffen has been honored with two Technical Achievement Awards from the Academy of Motion Picture Arts and Sciences: one for innovative product design, and the other for its unique lamination process which gives complete control over filter color and density. In 2000, the Academy presented Nat Tiffen, one of Tiffen?s founders, with a Scientific and Engineering Award for consistency in filter quality. Tiffen also received a 1998 Emmy Award for Engineering Excellence.
