For CPL Lens Filter:
A polarizer is different than most filters in that it is composed of two pieces of glass, mounted independently inside a round frame so that one can be rotated relative to the other. As it is rotated, it increasingly cuts out glare and haze. With an SLR, you can actually observe this change through the viewfinder. Polarizers reduce glare from water, glass, or any non-metallic surface. You can also use a polarizer filter to darken blue skies.
