I think you guys are saying the same thing. You cannot change the band of polarization in the sky. You can only change your composition to move the dark area of the sky. Keep in mind that this only applies at certain times of the day. If the sun were directly overhead, for instance, the polarized area would be on the horizon all the way around. Basically, you just have to look through the polarizer and make sure there is no dark band in the middle. If the sun is behind you (more or less) and at a reasonably low angle, you can get the dark area at the top of the picture that will fade to a lighter horizon, but of course you have to deal with your shadow in the pic. An easy way to know where the area of greatest polarization are is to piont your index finger at the sun and your thumb at 90degrees to it. Then rotate your thumb around the axis of your index finger. Your thumb points to the most polarized area.
