Had the camera line with this photo been close to or at floor level, I might have said no PSD. Toes that are slightly set back from the edge of a sandal would reflect enough light to be visible from a low enough angle, but no way from this height. The GA needs to bone up a bit in that area. It still, however, does not explain why the thong portions of the sandals were left out of the effect.
Thanks Caroline. You can see the original on the Abercombie & Fitch homepage.
