I've 8 600's and was thinking if there was a way to fire a different flash with each shutter release.
Situation is this, during first dance shots I backlit the couple with speedlites. Works well but I'd like to reduce the load on the flashes and take more shots in that short space of time.
I use the CP-E4's and use high ISO but with some Asian weddings the ambient temp is high and they sometimes fall over and overheat.
I don't need 8 there, (I usually use 2-4) but I was wondering if there was a way of doing it via the menu system and if not, if there is another option.
