The light of the sun is naturally partially polarized due to the reflection of electrons in air molecules, which causes the light to scatter into what appears as haze. A polarization filter aligns this directionally polarized light perpendicular to the reflected light and filters it, allowing for the absorption of a significant portion of this light. This results in a noticeable reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of the sky and foliage.
