Polarizing filters reduce reflections in exposures.
A polarizing filter screws onto your camera lens and has an immediate effect on the images that the camera captures. Polarizers reduce reflections. For example, skies are more defined and detailed with a polarizer because there is less reflective light to wash out the colors. Reflections in water and glass are reduced, allowing the camera to "see through" them to capture detail that would otherwise be reflected light. Polarizers, unlike other lens filters, have moving parts: two rings - a bottom one that threads onto the camera lens and one that can be maneuvered by the photographer.
Instructions
1. Remove any filter currently attached to the camera lens. Although polarizers can function while threaded onto a UV protective filter, it may work at a cost of image quality.
2. Attach the polarizer to the camera lens. Do not over-tighten the filter, or the lens threading may become damaged.
3. Point the camera at the subject and look through the viewfinder at the subject.
4. Focus the camera. If you are using automatic focus, hold down the shutter button halfway until the subject is properly focused, then switch to manual focus mode.
5. Turn the polarizer ring until the reflections on the subject flatten out or disappear. If you are shooting outdoors, you will also notice a deepening of the skies and clouds.
6. Hold down the shutter button halfway to meter the camera. Polarizers will lower exposure, so the camera (or the photographer, if he is using full manual mode) must compensate with a lower f-stop or higher shutter speed.
7. Press the shutter button to take the shot.
