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.
It is important to distinguish between UV-generated haze and that of air-borne particles, such as smog. The latter is made up of opaque matter that absorbs visible light as well as UV, and will not be appreciably removed by a UV filter. Haze 1 reduces excessive blue haze caused by UV light by absorbing 71% of UV.
It's great for all-around UV control. This filter eliminates UV problems from most situations where increased haze tends to wash out color and image clarity. This filter is designed for wide-angle lenses.
