you misunderstood my question: I know how the "magic eye" posters work and I never had a problem with them. That's what I was saying: I get the 3d effect here. What I don't get is a sharp image for the 3d effect. So I was wondering if I need to try and focus differently, or if maybe the images are different enough that - when merged by the left and right eye, there's a natural blurriness to the resulting 3d image.
