I've seen tutorials on this but none of them explained how to make it blend in so you can't even tell it was photoshopped into the picture. I use the magnetic lasso but there are always areas where it isn't smooth or part of the background is showing. Especially the hair. On top of that it will be better or worse quality than the picture I'm adding it to. Or it will be darker or lighter, etc etc. Can someone point me towards a tutorial that covers all of this and explains how to do this so it blends in perfectly.
