Are you denying the results of the experiment? Did you repeat the experiment to show that the results are wrong? Can you explain why you think the results are wrong? Did you do the video experiment that somebody posted above to prove that your own perceptions are omniscient? Until you can demonstrate that the expermental evidence is wrong, you're just arguing from incredulity. You keep making assumptions about information that you don't have. You don't know how far apart the photos were taken. It isn't about impugning human perception. It's about understanding human perception. If you think you know better than everybody else, do the experiments.
