I generally get what a polariser does, however I still have a couple of things I'm not 100% sure about
-does at polariser cut out reflections (from artificial lighting) in windows at night, when the inside is bright and the outside is dark?
-If i turn 90 degrees from angle of the sun's direction, turn polariser to max polarisation, does:
(a) if I move to a different location or angle, do I need to readjust the polariser again, to get max polarisation? (I believe to answer is no?)
(b) As time progress and the sun moves, do I need to change turn the polariser again, to get max polarisation? (I believe to answer is yes?)
