I did some art nudes with a friend last night using my studio flash gear. As
an experiment, I pulled out the flash meter and when I'd get my lighting dialed
in, I'd take a picture of the flash meter and a grey card.
As far as I can tell, the way it works is to fire the strobe. the f/stop that
it reads on the meter is the correct aperture for ASA 50 film. Point the arrow
on the dial at that aperture, then look at what aperture lines up with the ISO,
and that's the supposed correct exposure.
I will say that it never completely blew the exposure, but it was pretty
consistently different from the exposure that I ended up using, about a stop or
so under. In other words plenty of safe headroom for something really bright
in the picture, but not maximizing the SNR on low key digital photos. Shooting
at ISO 80 on the K-5, I think that I could feel confident that if I used the
flash meter, and didn't check the histogram, I would almost never blow a shot.
I am coming to the conclusion that it is a valuable tool to know how to use,
that there are situations that it can prove invaluable, but likewise, the
histogram is also a valuable tool, and I'd be foolish to rely on the flash
meter and ignore the histogram, if the histogram were available.
For those that would like to check for themselves, fluidr shows the exif data,
so you can see the flash meter reading, and my actual exposure data.

Those are about the geekiest nudes I've ever seen...

Don't lose heart! They might want to cut it out, and they'll want to avoid a
lengthily search.
