[QUOTE="WayneF, post: 541519, member: 12496"] [COLOR=#000000][FONT=Helvetica Neue] [SIZE=3]The human eye has very confusing properties. If we stare at the right end of a text scroll bar on the TV screen (or on this very line of text here), we cannot read the left end (not until we move our eyes left). Yet we say we can "see" the entire wall behind the TV (or behind this monitor). We might even claim a 180 degree view, but we can only read in a very tiny narrow spot where we concentrate our attention. Hard to pin down just what our eye can be said to see. I think the "normal lens" thing is that it shows us later the angular view that [B]we think we remember[/B] seeing when we were there. :) This scene "looks right" to us. But angular width of view is definitely Not the same thing as perspective. We could see same perspective if we stand in the same spot.[/SIZE] [/FONT][/COLOR] I disagree.
