I've started my adventure not so long ago and still need a lot of help. After few month of shooting in and sometimes outside the city I've decided to get a polarizer. I think I know how to use it (best result when being at 90 degrees) basically. But guy in the shop told me he never takes off his polarizer. So....
What I do is, I go out once a week to some remote location, sightsee and take lots of photos. I do not go to a preset locations on a specific time of the day to get the right light in this case (but I do go sometimes). I shoot city streets and noticed my pictures to be sharper and clearer even there was no direct sunshine to utilize the polarizer to its full potential (rotating the polarizer ring hardly saturates any colors). But still the pictures appear to me somehow better. Is it only me? Please, help me! Am I going mad? I know sometimes if I don't pay attention to this at all, some of the pics have half of the skyline gray and the other more blue. Should I keep it on my lens all the time and learn how to go with it or if I want to learn photography I should take it off and use only in specific situations (like removing reflections etc.)?
