But if true, then the situation of everything being simultaneously in focus 
is a "natural" and therefore acceptable thing for a stereo photograph
to have, and therefore defocussing where one isn't looking shouldn't
necessarily be an improvement, even for particular stereo photographs
where one's eye would be defocussed in the not-looked at areas.
