Q
How to tell when rotating if it is polarizing? I cannot visibly see any difference when rotating.
Answer Question
A
Try a different lighting setting. 93° from the sun to darken skies or solar reflections will be effected with a polarizer filter. I’m not sure what the seller means from their reply.
