The COKIN PURE Harmonie Circular Polarizer filter eliminates reflections of light from non-metallic surfaces such as water or shop windows. It also increases the saturation and the density of colours, such as a deep blue sky. The rotating front frame section of the filter allows the photographer to choose the intensity of the polarizing effect, by checking the picture through the viewfinder. The exposure compensation being 1 f/stop only, the view is not darkened unlike standard CPL absorbing usually 1,5 to 6 f/stops. Best results are achieved in sunny weather, when the camera’s axis makes a 90° angle with the axis of the sun.
The COKIN screw-in polarizing filter is also the thinnest in the world, with a thickness of 4.5mm and has a rotating ring to adjust the polarization.
