The UX II CIR-PL filter can be used with both digital and film cameras. It is used to control reflections from non-metallic surfaces such as water, glass, leaves and blue skies, increasing saturation and improving contrast. Polarising filters' structure incorporates a polarising film, sandwiched between two pieces of glass. The front part of the filter frame is able to rotate, allowing the polarising film to be positioned at the desired angle
