Light rays which are reflected become polarized. Polarizing filters are used to select which light rays enter your camera lens. They can remove unwanted reflections from non-metallic surfaces such as water or glass and also saturate colors providing better contrast. The effect can be seen through the viewfinder and changed by rotating the filter. The filter factor varies according to how the filter is rotated and its orientation to the sun.
If you're out walking on a lovely day - in the mountains or at the beach - and you want to get a fabulous shot of a cloud-filled sky or make the water seem more saturated, then a polarizer is the way to go. This filter is the best way to make the clouds stand out, increase or decrease the saturation of the ocean or increase or decrease the reflection off the water. You can also use this filter when shooting into glass or windows since it will, again, either increase or decrease reflections.
This filter is constructed from optical glass for clarity as well as
color fidelity and features an aluminum-alloy filter ring that can be
rotated in order to adjust the intensity of the polarization effect. To
prevent internal ghosting and reflections, each glass surface includes
five layers of anti-reflection coating. An additional hydrophobic
coating results in an improved beading effect when in contact with water
for greater cleaning efficiency.
• High-index / low-dispersion optical glass with HD technology
• Super Multi-Coated and heat treated glass to eliminate distortion
• Remove reflections, and increase color saturation, without affecting the overall color balance
• Can dramatically enhance a blue sky and make the clouds more prominent
• Used best at right angle to the sun
