Check this one out for example: http://homepage.mac.com/gapodaca/digital/blonde/blonde1.html
“On this image I was asked to make her look younger, take out the wrinkles and pores, remove the sneer, put some color back into her face… I also created a more natural look by bringing the hair down which was unusually high, probably due to the photographer using a long lens. This shows another extreme example of how far an image can be taken.”
Never mind plastic surgery, this is more like photo surgery in the extreme! Scary image!
Still, some of the other work is impressive.
There is another site I saw a while back, which was very very good – top rate in fact – what the guy achieved, with before and after shots; this is more impressive as the shots were the equivalent of ironing out the creases without any kind of ‘play’ on the image. Will go digging for it some time, though it’s ages since I saw it and don’t know where to start looking!
