Faith Hill and Redbook: Controversial photo re-touching

Faith Hill is on the cover of Redbook this month, and it's generating a lot of controversy. It seems that the image that appears on the cover was majorly touched-up -- any signs of wrinkles were removed and a bunch of flesh was skimmed off her arms (click here to see a comparison of the photos on Diet Blog.)

What do you think of the photos? I think she looks great before the touch-ups -- she looks much more natural. Her arms in the 'after' picture look impossibly small. And Faith Hill is unbelievably gorgeous and quite thin without any airbrushing -- why do they feel the need to make her look more perfect, more slender? Why mess with perfection?
