Yeah thaz right. The fill flash output would
be constant and the ISO would wander to
whatever :-(
No wonder I do everything in manual. Let
the camera brain intrude and everything I
ever knew doesn't work anymore.
I use AEL
toggle and Lumix "1-push" AE
cuz those are really manual settings that
do not very exposure once it's set. That is
all the "auto" exposure I can deal with. I
NEVER use auto ISO cuz I don't need one
more damnt variable !
Apparently, I can't even THINK in terms
of auto ISO.
=========================
What would actually happen if you follow
my method is that as the scene brightens
ISO goes lower so you'd have more main
exposure but less fill flash in the mix. For
the opposite the main exposure would be
proper due to auto ISO but the fill flash
will be more than a weak fill-in. In most
cases the overall exposure would be good
but the balance of ambient to flash would
vary according to how ISO is responding
to changes in scene brightness.
So .... my instruction would work only in
M-mode with a
fixed ISO and in A-mode
with a
fixed ISO but only if you can avoid
letting A-mode outrun your synch speed,
which is a too-likely occurrence :-(
