A Circular Polarizing Filter that blocks or reduces polarized light reflected from glass, water, and reflective non-metallic surfaces such as plastics, ceramics, polished wood, and paper. Suited to increase overall contrast in low-contrast situations or when the subject is on the other side of a window, underwater, or inside a transparent container. Can also be used to block reflected or dispersed light when shooting out of doors, intensifying colors and making the sky appear bluer. |
