As the filter is rotated, the partially polarized light is blocked and the glare is reduced. The photographic secret of capturing a vivid blue sky as the backdrop of a beautiful foreground lies in the physics of polarization and Polaroid filters.

a brand of material for producing polarized light from unpolarizedlight by dichroism, consisting typically of a stretched sheet ofcolorless plastic treated with an iodine solution so as to have long,thin, parallel chains of polymeric molecules containing conductive iodine atoms. It is used widely in optical and lighting devices toreduce glare.
