LOL! Well, I found it a pain to use cos I'm not very patient and the curves are very sensitive so VERY minor changes to the curves are needed really unless ur photo is really bad! So it's kinda hard to adjust the curve the way u want! Levels are, for me, the perfect tool!! I adjust my images in a few mns with the levels tool and it looks so good!! Here's the proof! Surely it's not perfect but I'm very pleased with it for now! ;)
