Tiffen 55mm Circular Polarizer Polarizing Lens Filter and Lens Cleaning Brush Kit

Polarizers provide color and contrast enhancement. Reflected light shows up in the image as whitish glare that washes out the color in an image. A Polarizer corrects this problem and producesdeep, dramatically blue skies. It also removes glare from non-metallic surfaces, such as windows and water. Color saturation in general, especially outdoors, can be improved significantly.A Circular Polarizer has the same effect as a Polarizer and is used on cameras with beam splitting metering systems commonly found on auto focus SLR's (for most 35mm auto-focus cameras see your camera manual).
