    Polarizing filters improve photographic effects by reducing reflected light, which adversely affects image definition. They are used to eliminate reflections on glass, water, etc. and to make the sky more blue as well as increase the overall contrast for scenes captured in dull lighting or low contrast conditions.

    Close-up lens (or filters) help you to take close-up macros of objects by decreasing the minimum focusing distance of a camera lens
