OUR PART # 72CP
72mm circular polarizer filter from Tiffen. Polarizers provide color and contrast enhancement. Reflected light often shows up as whitish glare that washes out color in an image. A polarizer corrects this problem producing deep, dramatic blue skies. It also removes glare from windows and water. Color saturation can be greatly improved.
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).
Area of sky most effectively polarized with a Circular Polarizer:
Point your index finger at the sun. With your thumb extended at a right angle (90°), rotate it around the axis of the index finger. It will point out the band of deepest blue from horizon to horizon.
