Canon Circular Polarizer - 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.
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
If you're shooting black and white and want to
simulate a threatening storm, try throwing on a #25 Red filter. The
vista will take on the appearance of an imminent, ominous storm.
with a UV or Skylight Filter, a polarizing filter should be a part of
everyone's gear bag. It can turn a run-of-the-mill image into a
stunning, creative photo by increasing color saturation.
Note! Circular polarizers are
specifically designed for use with auto-focus SLR cameras (They will
also work on manual systems and video cameras without problems)
