I'm new to CPL. Bought a decent one (b+w xs-pro 82mm) and tried it the other day. I rotated the front such that my foreground appeared more saturated with less glare. What I noticed was that the sky was partially/unevenly darkened. I was not using an ultrawide lens. I was at 24mm. The sun was more or less over my right shoulder, 90 degrees to my camera axis. How can I saturate the sky more evenly? I'm sure it's a matter of technique and not a fault of my CPL, and I'm hoping someone could shed some light. Thanks for your help.
