I guess I didn't make myself clear. I meant two separate exposures at
possibly different apertures but only a single photo. Start the long
exposure for ambient at the aperture for flash. Manually fire the flash
off the camera. Continue the long ambient exposure and change the
aperture if desired. I don't know if a digital camera with native AF
lens will allow an aperture change so you may need to use a manual lens.
Of course, if you don't want different apertures it's all more normal.
But consider that you can remove the flash from the camera and fire it
manually and do it many times if desired. That's called light painting.
Just keep yourself out of the photo while walking around with the flash.

Just recall that the flash and ambient exposures are separate. If the
ambient exposure is a long one there's no reason why you can't make them
at different apertures. Experiment with the flash exposure at the same
ISO you intend to use for the ambient. Play with the aperture for the
flash till you get it to your liking. Then put the two together adding
the ambient after the flash and at a different aperture if desired.
So what you're saying is to take one photo of the sky itself and then
another of the nearby landscape that's illuminated with the flash, then combine
them? That seems like an interesting process. I was thinking of doing it with
a single photo.
