When I was ten years old I was a pathetic chemistry and physics swat and that's what led to me getting involved in photography. Back then photography was 90% chemistry but apart from that I studied the whole history of photography as well so that as the years went by, I gained more insight into photography. Later I worked for twenty seven years in a large corporate situation and now despise the whole chemistry scene with a passion.
You are quite correct in your description of light and how it either passes or gets blocked by a polariser. If memory serves me right, the light reflecting off a metallic surface is called 'specular' light and this is not affected by a polariser. Only light of a single dimension or flatness is blocked by a polariser. That's enough of that...!!!
Regarding the taking of stunning Hi-Fi photographs... it is not in the camera... it is in your head. The only thing restricting you is your own imagination.
