Canon 72mm Circular Polarizer Glass
Canon 72mm Circular Polarizer Glass Filter
Creates dramatic sky/cloud contrast. Saturates colours without changing colour
balance. Mount rotates to control amount of effect. Light rays which are
reflected by any surface become polarised and polarising filters are used to
select which light rays enter your camera lens.
It allows you to remove unwanted reflections from non-metallic surfaces such as
water, glass etc. They also saturate colours and increase contrast. Polarizers
come in two variations but have the same effect.
