I'm gonna have to disagree with that statement.. PP might make a huge difference in certain types of photography (HDR, etc). But in regular photography (like the shots above), it doesn't. Obviously, there might be some "editing" involved, but the way a photo turns out isn't dictated mainly with editing as you said. Alot of people don't do much besides a simple resize, while others do much more. And lenses can make a HUGE difference.

To the OP - Very nice shots
