UV filter

The UV filter absorbs invisible ultraviolet light from the sky, which can cause blur and to which many colour films react with a blue cast. Actually, the filter should be referred to as a UV blocking filter because there are also UV filters that allow UV radiation to pass through and block all other types of light. Among photographers, the term "UV filter", however, is always used to describe UV-absorbing filters are ideal for photography at high altitudes, at sea and in regions with very clean air. The pictures gain brilliance and disturbing blue cast is avoided. Apart from the withdrawal of the blue cast nothing else changes. The colour rendering remains the same and an extension of the exposure time is not required. The UV filter is therefore very suitable for permanent mounting on the lens. Your filter can be screwed in front of the lens as protection against sand, sea water, dust and the like. In most cases, you would prefer to replace the filter, then a much more expensive lens. The filter is recommended for use in combination with analogue colour, black-and-white and digital recording.
