Okay, I bit and looked up the ad for myself. I was pretty convinced that the
pictures weren't really a "stereo pair" in any real sense, but I was curious
about them. Sure enough, the "subtle differences" in the ad simply refer to the
fact that in one picture the girl is staring into space, and in the other she's
looking at *you*. But interestingly, the model had shifted her weight just a tad
between the two takes, and as a result there is a marked, if quite unrealistic,
stereo effect when the two pictures are fused. It just goes to show how subtle
the differences have to be to create eye-grabbing stereo.
