The truth about polar­iz­ing fil­ters is that every pho­tog­ra­pher should have one in his/her bag at all times. It is pos­si­bly THE sin­gle most impor­tant and‚ use­ful photo acces­sory you’ll own. When there is light out­doors, this fil­ter is on my cam­era the vast major­ity of the time.

A CPOL (cir­cu­lar polar­iz­ing fil­ter) can be used any time you’re in the out­doors, espe­cially in the bright sun. It reduces reflec­tions, and deepens/saturates col­ors like a blue sky. In bright sun,‚ you’ll often get skies that are blown out if you don’t use this fil­ter. It makes the sky much bluer and richer look­ing in many cases with­out really affect­ing the other tones in the image. You will note the great­est results when the sun is low in the sky (so early morn­ing and later afternoon/evening). The CPOL will not help your color and sat­u­ra­tion much on over­cast days, or when the sun is high in the sky.
