Product Description Adopted 28-Layer multi-resistant double coating technology with the K&F 82MM XC16 Nano-X B270 CPL Super Slim Circular Polarizing Filter, the green coating helps effectively reduce filter surface reflection and the ghosting while making the filter anti–scratch, water repellent, oil and dust resistant. • Polarizers provide color and contrast enhancement. Reflected light often shows up as a whitish glare that washes out color in an image. A Polarizer filter corrects this problem by producing deep, 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. Think of it as sunglasses for your camera. • A Circular Polarizer has the same effect as a Polarizer and is used on cameras with beam splitting metering systems commonly found on autofocus SLRs (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.
