The B+W Filter Company has been manufacturing optical filters for over 50 years. Their filters use Schott optical glass from which the B AND W filters are diamond cut, precision ground and then polished to ensure flatness on both surfaces and uniform thickness throughout. These filters block the invisible UV component of daylight, which can cause blur and to which many colour films react with a blue cast. These 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 removed. Because the glass is colourless, colour rendition is not changed, other than he elimination of the unwanted blue cast. No increase in exposure is required. This makes a UV BW 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 analogue colour and black and white as well as digital photography. In FPRO mount only.
