Last night, I attended a "portrait workshop". We were shooting at the
beach, at the end of the day. It was still very bright, and in the
shade of a lighthouse, some fill was required on our models' faces.
No problem. I had the AF540 on my k-7...using aperture priority mode,
and -1.5 Flash EV, I took some shots. Gah. Way overexposed. I
fiddled, set the flash to high-speed sync, and tried again. Still
hot. I proceeded to try several other manipulations... none really
working, until I settled on a fully manual operation for exposure, and
flash (1/16).
It shouldn't have to be this way, though, right? I should be able to
use pttl to provide (more or less) the right amount of fill, yes? I'm
even pretty sure I've done it successfully in the past, though it
would have been with the AF360.
What am I doing wrong?
Thanks,

Unhappily, yeah, P-TTL is easily freaked-out by the light conditions.
I've had it work, so it *can*, but under extremes, and I think back
light is a "Pentax extreme", it won't.
But where were you applying the -1.5 comp: on the K-7 itself (ie in the
flash menu), or on the back of the flash? This makes a big difference.
I find that applying exp comp on the flash generally works better then
on the camera.
