Speaking of boggling, I met a fellow selling photos on the street made
with medical camera -- the kind they stick down your nose or up your
whatsis to take a picture of your inner self.
He had a friend who worked in medical imaging, he himself was doing a PhD
in computers... and they were using many types of high-end lab devices to
get negs for prints ... To that point, however, the imagery looked (to my
eye) quite conventional.
