Umm.. ok so when I was bored, and trying to figure out how to use Corel Photo Paint better... I messed around with this tree. I think I put it back in a time by a few months:P
BEFORE: (raw image)
AFTER: (I messed with it)
I'm still fairly new at this, so I've just been experimenting with what different color adjustments and such do.
EDIT: Err... loss of quality also involved here I guess, oh well:P
