The benefits of a Circular Polarising filter

Circular Polarising filters allow you to control the direction of light in your photographs.
When capturing light there are many randomly scattered light rays that can cause reflections and glare.  A polarising lens will allow the photographer to select which light rays enter your camera lens.

Polarisers also have the added benefit of enabling colours to become more saturated and appear clearer with better contrast. Giving the effect of bluer skies and white clouds with detail without affecting the overall colour balance in a shot.
