Kelly, I've been thinking about how I would attempt this. Of course I'm probably backasswards on this. But I would simply meter the sunset in evaluative metering mode. Lets say that on 400 ISO its f5.6, 1/30th. Then I'd set the flash to ISO 400 f4.

If I understand the Metz system, then the thyrister knows when the subject is properly exposed. Therefore the red indicator on the back of the flash and it shuts off. Now if you're close in settings on the camera to the original metering, then you should be ok. If anything speed up the shutter to under expose the sunset a little.

Does this make any sense? The more I read over it and think about it the more confused I become.

I'm going out and will try it tonight. I don't think we'll have any nice sunsets in the hills of east TN. But, I'll try it anyway.
Pics to come later.
