Jesse lad,

your thinking about stuff like this will drive you crazy,  not to mention most
of the picture taking LUGGERS. However, some of the techie types will love it
and consider it a mind blowing challenge for about ten days trying to figure
out the answer.

When in reality,      Don't think about it!  ...........just shoot the damn
picture and it works!  The more you think about things like this the more good
old fashion picture taking time is frittered away! Photography is supposed to
be a fun thing,  not a morning brain exercise! :-)
