Cokin X164 Circular Polariser Filter

The Cokin Circular Polariser filter was designed for cameras with a polarising half mirror (split beam metering), and for digital cameras. The Circular Polariser filter increases the colour saturation of blue skies and removes the unwanted reflections from non-metallic surfaces such as glass and water. Use an angle of 45 from the subject and turn the filter into the holder to adjust the polarising effect.
