Hi,
I frequently run into a color shift in skies and struggle to even them out. I often abuse the polaraizer but have been using that for less sky shots but still find a color shift when at 90° from the sun. Seems worse at sunset/sunrise.
I shoot a Nikon D300 and have taken to NX2 although I have PSCS3 and LR at hand as well.
Luckily I've noticed this even in some real pros works so maybe I'm being over critical.
Here's the latest one that bugging me though: (in all honesty this one probably had the polarizer on as I bracketed with and with out but the breeze was worse than I thought and out of 12 shots only this one was still enough for my liking).
Thanks,
Warren
