The B+W 25.5mm UV Clear Fujinon Iconix is designed to block the invisible UV component of light from the sky, which can cause blur and to which many color films react with a blue cast. The B+W 25.5mm UV Clear Fujinon Iconix could be called a UV-Blocking Filter, because it is a filter for technical applications that pass UV radiation and block all the other wavelengths. Nevertheless, the short term ﾓUV Filter" has become established among photographers. UV Filters are ideal for photography in high altitudes (in the mountains), by the sea and in regions with very clean air. The pictures gain brilliance and disturbing blue casts are avoided. Because the glass is colorless, color rendition is not altered, aside from the elimination of the unwanted blue cast, and no increase in exposure is required. That makes a UV Filter very suitable as protection of the front element of the taking lens against dust, flying sand, sea water spray and the like, and it can be kept on the lens at all times. It is recommended for analog color and black-and-white as well as digital photography.
