Flash metering is an entirely separate system, using a center-weighted
sensor measuring illumnation on the actual film.

It will meter exactly as it would if you didn't have the flash up.
If you are set to spot metering, it will use spot metering.  If you
are set to multi-segment, it will use multi-segment metering.

Again, the flash metering is center-weighted.   If you know that
the item that will be illuminated by the flash is far enough off-
center that it will be reduced in significance by the flash
metering, you want to adjust the flash balance.   you can do this
by setting the flash exposure compensation (a Pentax Function).
