A Polarizing Filter, used for both color and black-and-white photography, is colourless and does not affect colour balance, but filters out light with a particular direction of polarisation. This reduces oblique reflections from non-metallic surfaces, can darken the sky in colour photography (in monochrome photography colour filters are more effective), and can saturate the image more by eliminating unwanted reflections.
The main function of the Circular Polarizer filter (CPL Filter) is eliminating the scattered light in the air,as well as the reflected light of the metal ,glasses and liquid.It is only allow the parallel light through the lens only,so that the camera can get a better picture such as blue sky,white cloud,clean water and so on. When you rotate the CPL filter in its mount, the effects will show up immediately.

Why use a Polariser?
  • Polarising filters are used to manage light at wavelength scale, and if magnified could be a likened to a series of microscopic slats.
  • In use, as the filter is rotated, it either transmits or blocks the waves of light that are vibrating in particular orientations. When light from the sun bounces off a flat non metallic surface, such as glass or water, it becomes polarised – i.e. all of the reflected light waves vibrate in the same plane. This reflected glare can be removed by the polarising filter.
  • Rotation of the filter will be needed to find the optimum position of the Polariser. In photographic terms this can render water or glass transparent, and gives the impression of saturating colours in a scene, because much of the reflected glare from the subject is removed by the Polariser.
  • On a clear sunny day, much of the light in the sky is also polarised, and the filter will give a very strong blue effect when used at 90 degrees from the sun – any white clouds will stand out impressively.
