here's the set, and it is most definitely shopped, besides the suspect shading below the breasts, if you line up the original and the shopped versions side by side, her breasts in the original are much smaller (though still fantastic) http://www.primecurves.com/september-carrino-cooking-nude/
Could be my imagination, but when I size the pictures to the same ratio (looking at the pot for reference), her breasts look larger in the attachment than in the gallery. Could be my imagination though. I tend to have an excessively skeptical eye.
Ok...the pics are now side-by-side. There is a subtle difference, which could be attributed to the GF pic (on the left) being stretched horizontally. I don't know if I would call it photoshopped by definition. You all decide. http://www.imagebam.com/image/3c254382368430
