By reducing the light reflected from non-metallic surfaces, polarizing filters allow direct shooting through glass windows and reduce the effect of glare from water surfaces and sunlit trees and grass. In outdoor shooting, the filter can even deal effectively with light reflected on steam or airborne dust particles to enhance the sky's blue color.
