A polarizer is a must-have optical filter for landscape photographers as it can darken blue skies, increase color saturation and bring out details in clouds.

It provides color and contrast enhancement that some movies are even shot throughout using the polarizer to eliminate reflections of human skin with dramatic effect.

A polarizer also removes glare from non-metallic surfaces, such as windows and water.

Color saturation in general, especially outdoors, can be improved significantly.
