If you use a slave cell, you can use the internal flash as a trigger. If you think the flash is too bright, tape some tissue over it. The slaves will still pick up the light pulse.

I am assuming, Paul, that any compacts that can do this will use a process similar to that of dSLR cameras - i.e. at shutter speeds above the normal maximum sync speed, you have to use a flash mode that, in effect, fires a burst of very short flashes.

The main disadvantage of this process is that, the faster your shutter speed (OK - I know that "shutter speed" is a totally erroneous term, but everyone uses it), the lower the amount of light captured from your flash.

For example, with my Nikon D800, the Auto-FP flash mode gives me almost full power at a shutter speed of 1/320th but I am down to quarter power at 1/1000 and one-sixteenth of full power at 1/4000.

I assume that the same sort of rapid power reduction will apply to any compacts with a similar flash mode.

Sorry Paul. Misunderstood your question. Can't help I'm afraid.
