Tiffen UV Protection filter Film, as well as video, often exhibits a greater sensitivity to what is to us invisible, ultraviolet light. This is most often outdoors, especially at high altitudes, where the UV absorbing atmosphere is thinner; and over long distances, such as marine scenes. It can show up as a bluish color cast with color film, or it can cause a low contrast haze that diminishes details, especially when viewing far away objects, in either color or black and white. Ultraviolet filters absorb UV light generally without affecting light in the visible region. Using a Tiffen UV Protector on your Digital HD DSLR While the UV Protection filter has served its purpose in the film era for many years it will still continue to be one of the most popular choices in accessories today. Digital cameras have blocks, auto correction and digital filters that combat the bluish color cast therefore making the UV Protection filter a simple protector for your lens to combat dirt, finger prints & that fateful knock or drop.
