Circular Polariser – When a light ray is reflected, it becomes polarised. Polarising filters are used to select which light rays enter your camera lens. They can remove unwanted reflections from non-metallic surfaces such as water or glass and also saturate colours providing better contrast. The effect can be seen through the viewfinder and changed by rotating the filter. The filter factor varies according to how the filter is rotated and its orientation to the sun.
NOTE: Circular polarisers are designed for use with auto-focus SLR cameras (However they will also work on manual systems and video cameras without any issues).
- This filter eliminates ultraviolet rays to remove haze from outdoor shots as well as polarising the light to remove reflections, and increase colour saturation, without affecting the overall colour balance.
