Haloing drives me bonkers. BONKERS. I've done one HDR, and it was of a S&W airweight. It looks decent, but I need to figure out more on my camera in general before moving anywhere with HDR (I really just wanted to figure out the autobracketing, so I went ahead and compiled it too.)
I heard someone at the photo competition say "If a picture is taken outside, and it's not HDR... it wasn't worth taking." Funny, all he had entered were HDR landscapes with ghosting and haloing everywhere, WAY overcooked. He didn't place, either. =P (This is a guy who should know better, too!)
