Effect of polarising filters
Posted: Sun Jan 10, 2021 2:38 pm
During what I remember as a very brief summer I sent away for a pair of clip-on sunshades. Very thin tinted plastic, they surprised me by giving the impression of separating the planes of a middle-range view in the garden - foreground, middle and more than 20 feet, say in a way that I have never noticed with tinted specs. Would that be an effect of the plastic polarising the light or interaction with artificial lenses in my eyes (cataract replacements), do polarising filters have any similar effect in photographs/film or video? My specs are not 'strong' but I do need prisms in them to correct double vision. My daughter needs VERY strong specs (Very short-sighted) but no prisms and she got the same effect. Any ideas? Seems like one for Tom! Happy New Year everyone.
