| Mar 11, 2011 at 3:48 | comment | added | Jerry Coffin | @sat: When light reflects off the surface of a material that isn't electrically conductive, it gets polarized. A crossed polarizer in front of the lens will block (most of) that reflection. There are quite a few filters that purport to give the effect of polarization, but most just bump up the saturation. | |
