3 Piece Professional Filter Kit (UV-CPL-FLD) for Canon Rebel & Canon EOS Cameras UV filters reduce haze and improve contrast by minimizing the of ultraviolet rays entering the lens and are ideal for areas of high altitude or snow, eliminating the undesirable blue cast. CPL filters are used for removing unwanted reflections from non-metallic surfaces and improve clarity in distant objects by cutting through haze and increasing color saturation. FLD filters are great for shooting photos under fluorescent lighting and add warm natural lighting to rooms that would otherwise be washed out by unappealing fluorescent lights.
