Light rays which are reflected by any surface become polarized and polarizing filters are used to select which light rays enter your camera lens. PL-CIR (Circular Polarizing) filters have the same effect, but it is important that you choose the correct version for your camera. They allow you to remove unwanted reflections from non-metallic surfaces such as water, glass etc.
Features include:
Remove unwanted reflections from non-metallic surfaces
Enables colors to become more saturated
Increases contrast
Hoya's polarizing filters do not affect the overall color balance of a shot.
