I hate to break it to you guys, but 99.9% of every professional photograph is photoshopped. Before Photoshop, it was done with an airbrush in a lab. If it's not noticeable then it was done by a pro.
The original photo in this thread was mangled by an amateur. Bad lighting compounded by atrocious attempts to modify it has rendered it a mess.
Shame to mar such a beautiful model.
