Okay, now you've gone and made my brain hurt! Maybe I should stick to
Hypers. ;-)

Next question: photographing an insect, macro, with a very shallow depth of
field and, say, a distant background of shrubbery. If the background is this
out of focus, would the individual angles of view of the subject be the only
concern in determining the base for depth perception? Or is there still
enough depth information in the out of focus areas to be useful? Also, in
cases like this, is it better to toe in to keep the subject dead center for
each view? I'm guessing less or no toe in IF the background is important,
but yes if it's not.
