"He spent all that money on photography gear and still doesn't understand perspective..."
I understand perspective just fine, which is why I've always been the photographer and graphic designer for the websites I've run or managed. I also understand parallax just fine. And I also understand that up close or far away, the bump still shows up, unless you're BLIND. Funnily enough, I have macular degeneration in my natural cameras, and I can still see the bump, either up-close to my face, or far away, same flat edge-on viewing angle.
And that's WITHOUT my glasses.
