Last week, or maybe the week before, I posted
about the flash I'm using with the *ist D on
the microscope. The voltage on the trigger
when the unit is fully charged is 6.5V and
the centre wire is positive. Is this the
right way round? The flash still only fires
once -- unless disconnected between each
picture. But there's another problem. With
ISO 200 film, on the Wild MPS camera, the
exposures are good. But all the digital
pictures are dreadfully underexposed at 200.
Is there an explanation for this -- I can't
think of an obvious one. The optical setup is
the same as before.
