I've been trying to figure out what the "best" factor to use is for the
camera angle keyword. In the PovRay distribution (3.6.1), the scene files
seem to imply that the authors favor "angle 35" to depict a "normal" view.
I know its a complicated subject, not as simple as one might expect. I've
been surfing for research. I can't find an answer that "I feel comfortable
with". For one thing, humans percieve *binocular* vision (approaching a 190
degree field of view in the x-z plane *if you are young* and not a crusty
old thing like me) - whereas when considering *just one eye* things are
different (where is Popeye when you need him?). And the FoV in a 35mm
camera using a 50mm "normal" lens (which actually approaches what I want to
depict in PovRay - and even then a "normal" lens isn't really "normal") is
different then even just one human eye.

Discussion?
