Amy, I'm a Nikon shooter, so a bit biased here!
Besides my pro camera, I've also used a Nikon Cool Pix and they are really great cameras. As mentioned, though, it's not so much the camera, as you learning it's functions and how to use them to best suit what you're doing.
Buy a camera that feels good to you and that has some custom capabilities and then learn and understand them and put them to use. And a good editing software is great for touchups. But, if you get the image right in the camera there will be minimal touch ups and that's really the goal!
Good luck!
