Uneven polarized skies

Some time ago someone posted a fairly easy way to even the color on a sky that was unevenly polarized, i.e., with a super wide angle. But I cannot locate that thread. Anyone remember it, or how to do it?

I have used this a few times for cloudless skies.
Fix Uneven Skies

Very timely post Ed...I was having issues with this too. Thanks to you Doug for the link!

Funny, i 'discovered' that method when i was trying to come up with a way a few years back to fix a polarized sky problem. It usually works pretty well. The selective color method (i think John M might have told me about that one) also works in some cases. But fixes are a PITA, im a lot better off now that im a lot more careful in the field these days, live view helps too, just turn the CP while watching in live view and no worries at all!

Thanks, guys. I usually avoid this issue but sure missed it on an image this fall that deserved a better fate! This does work reasonably well but in the end it sure is a lot better to avoid the problem at time of capture! thanks, again.
