    A polarizing filter is made from a thin sheet of polarizing material which is laminated between two circular pieces of glass and mounted in a frame. You can then rotate the filter while it’s fastened to the lens, affecting the filter’s angle of polarization and thus altering the amount of polarized light in the scene which can pass through. Also, regardless of angle, a polarizer reduces the amount of light entering the lens - it can act as a neutral-density filter in this regard, typically costing a little more than a stop of light.

    Polarizers are useful for cutting reflections from water and glass (ie: non-metallic) surfaces. They’re commonly used for cutting reflective glare off of windows, or for taking a photo of a lake without a reflection on the lake surface, for instance. They can also be used to increase colour saturation of blue sky (since light scattered by Rayleigh scattering is polarized) and of certain types of vegetation. Note that the effect of a polarizer on the sky varies depending on the angle to the sun (Brewster’s angle). So a very wide-angle lens with a polarizer will demonstrate differing amounts of polarizing across the frame.

    There are two basic kinds of polarizers - linear and circular. Linear polarizers work well with manual focus cameras, but they interfere with autofocus cameras. Circular polarizers contain another element - a “quarter wave” plate - which ensures compatibility of the filter with autofocus systems. So if you’ve got an autofocus camera be sure to use only circular polarizing filters.
