(…) The Eye is Not a Camera System
Having gotten the answer to the original discussion, I could have left things alone and walked away with yet another bit of fairly useless trivia filed away to amaze my online friends with. But NOOoooo. When I have a bunch of work that needs doing, I find I’ll almost always choose to spend another couple of hours reading more articles about human vision.
