Can you notice a CPL filter on a 360° shot while it's on the "default" position?
I know that the effect of a CPL filter only really takes effect in a 90° angle to the sun. Because of that it also shouldn't be used for panorama pictures or videos, due to the fact that each of the photos would have a different strength of the polarizer effect and would therefore look strange in the end product.
I wonder if I could leave the CPL filter on, all the time? In other words, while a CPL filter is in its default position, does it look the same 360° all around, or would it still look different in a 90° angle to the sun, compared to facing the sun directly?
Just wondering if I have to put on the CPL filter every time I want to get rid of some glare, or if I could also just leave in on, while doing some other shots in between, where the effect isn't needed or wanted.
