LEE 105 MM CIRCULAR POL FILTER

LEE 105mm Circular Pol Filter

Polarising filters are used to manage light at wavelength scale, and if magnified could be likened to a series of microscopic slats.
In use, as the filter is rotated, it either transmits or blocks the waves of light that are vibrating in particular orientations.
When light from the sun bounces of a flat non metallic surface, such as glass or water it becomes polarised - ie: all of the reflected light waves vibrate in the same plane.

This reflected glare can be removed by the polarising filter as it is rotated to the optimum position.In photographic terms this can render water or glass transparent, and gives the impression of saturating colours in a scene because much of the reflected glare from the subjectis removed by the filter.
