Few days ago I experimented with low-light photography and find one interesting way based on frequency separation. High ISO makes much noice, but lowering it makes adding more light and therefore light sheme changes.
Idea is to get low frequincies from frame with low light (it brings proper lights and colors) and high frequencies from frame made with flash. Of course there are some restrictions such a flare from flash, but generally it works.

Now question:
How to make to shoots with different settings in sequence?
For example:
ISO 3200, 1/50 and no flash
and immediately next frame with
ISO 100, 1/200 and flash.

P.S. sorry for my english =)
