Since i started in art school, i can't even begin to tell you how much you can alter a photograph or digital image using photoshop or another imaging program. Anyone can clear up skin, remove birthmarks, smooth cellute, etc.... pretty scary... in a way i think it does give ordinary people (who don't understand that such programs exist) a false sense of 'reality'... now when i flip through magazines, i just roll my eyes at what they do... personally, i find it refreshing to see real people in ads, or on television now...
