Does this refer to a reference to a light reading of 1/125th sec. (if memory
serves me right) at an aperture of 16 on a very sunny day (I think I've read
this somewhere) ?!?
If this is way off base, then please could someone explain what it is
exactly?
Cheers!

Olaf,
"Sunny 16" just refers to a good starting point to figure an
exposure. Apparently, I assume, this came from the days before there were
in-camera meters, you had to bring along your meter. If you forgot to bring
it, you could guesstimate from the sunny 16 rule. You would choose a shutter
speed equal to the film speed.
F/16 refers to a bright sunny day. You would then open up the lens as
conditions (clouds, overcast sky) dictated. The 1/125 at F/16 is OK if your
film speed is 100 or 125.
