"So my understanding of this is as follows: I meter for the sky to create the beautiful sunset. If the meter in the camera suggested ISO 100, f/11, 1/60, then I would need to make adjustments for a larger aperture in order to drag the shutter and get more ambient light in. So, If I kept ISO at 100, f/8, that would allow for 1/30...which is getting closer to a setting that would allow for a richer sunset. "
Yes, that is what I was looking for. I agree with that theory. The flash is going to expose for the couple and it's shutter speed that's going to allow the ambient light in. It makes sense and now I have a better understanding of what you were going for.
The one thing I will caution about tho, is keep an eye on those flash values. One can take all the readings of the ambient light they want, but if the couple is out of the flash range, it won't work. I know Metz recommends the subject be in the middle third of the maximum flash distance for best accuracy. (I'm not saying that's the case in your pictures, just bringing it up

)
I agree with about keeping this thread open. I haven't tried this particular set-up in over a year and that was on film. When I can I am going to make an attempt or two of my own and will post the results.
