A UV blocking filter or ultraviolet optical filter prevents ultraviolet light transmission. UV filters are commonly used in photography to reduce the level of ultraviolet light that strikes the recording medium. Historically, photographic films were mostly sensitive to UV light, which caused haziness or fogginess, and in color films a bluish hue. Therefore, as a standard, a UV (blocking) filter was used, transparent to visible light while filtering out shorter ultraviolet wavelengths. However, newer photographic film and digital cameras are highly insensitive to UV wavelengths.
