I thought this is a perfect picture to demonstrate the clone tool. It took sevral hours, but the finished product came out pretty well. As you can see I cloned the heck out of the leaf. What was once a browned and dying leaf is transformed ;) into this healthy specimen. I changed a very overcast day into a beautiful sun shiny day. To do this I picked a color (the sky, in pieces) and pumped up the saturation and adjusted the levels. There maybe a little to much contrast....but it is kind of hard to tell on my old dino screen. I think my fav. part is how the sun shines through the leaf adding a nice glow.
