The light from the sun naturally\nbecomes partially polarized due to reflecting off electrons in air molecules,\ncausing the light to scatter into what appears as haze. A polarizing filter\narranges and filters, this directionally polarized light perpendicularly to\nthe reflected light, allowing for the absorption of much of this light. This\nresults in a noticeable reduction of glare and reflections from non-metallic\nsurfaces and an increase in the saturation of skies and foliage. A circular\npolarizer only differs from a linear polarizer in that it contains a quarter\nwave plane in addition to the linear polarizing filter. The addition of this\nquarter wave plane is to circularly polarize the linearly polarized light for\nthe use of auto focus and exposure functions. Due to how the light is broken\ndown and filtered with a linear polarizer, auto focus and exposure accuracy\nbecome skewed during use. When the light becomes circularly polarized, it\npermits the use of these functions. Helps to reduce reflections and glare by\nfiltering out light that has become polarized due to reflection from a non-\nmetallic surface. Polarizing filters arrange and filter, directionally\npolarized light perpendicularly to the reflected light, allowing for the\nabsorption of much of the light.
