I'm curious as to what goes into producing the three-dimensional effect, and thought that maybe it could be achieved by juxtaposing slightly cropped versions of an existing image: one with a small amount cropped off the left side, and the other with the same small amount cropped off the right side.
While I was able to throw my vision, the true 3D effect wasn't apparent in the image.
There's obviously something more to it, and I clearly have some reading to do. :-)
