And then there's the more common but no less mysterious "B" setting,
which I've always heard "translated" as "bulb", which holds the shutter
open as long as you hold the shutter release button.  Is this intended
for syncing to flash bulbs?  (I always used it for exposures longer than
the camera wanted to time itself, like those pictures of the full moon
shot with long f >= 8 lenses for ~30 seconds with Tri-X that we then
pushed to about 1600ASA...)
