It was my understanding that reflections in glass can be either polarized or non-polarized, or a mix of both. If you use a polarizing filter on a camera (e.g. when taking photos of artwork through glass, or shooting over water that you want to see into), you will often find that it does not remove all reflections. https://en.wikipedia.org/wiki/Brewster%27s_angle |
