I am new to this so please don't shoot me down if this is simple.

I have a d7000 to do this.

I am trying to work out how I can shoot as quickly as possible with a flash. The flash will be used to fire other flashes so if possible I can use a weaker flash output to produce the trigger

Any help much appreciated
 
If the other flashes are set to an optical slave mode/SU-4 then they should just fire whenever they detect a 'fire' signal (a burst of flash) from the onboard flash.

However, the ability to fire flashes continuously also relies on the power source. AA batteries run down (obviously) but the ability to keep recycling, especially at high power outputs, is another factor that inhibits a flash's ability to fire continuously.

Basically, the 'flash chain' is only as strong as its weakest link and that will be the flash with the worse recycling speed and weakest batteries...
 
Thanks, I understand exactly what you are saying here, what I am trying to work out is how can I get my onboard flash to fire at its quickest possible rate?

This is basically for underwater photography, the strobes/flash are set off by optical cables, I just need to trigger them. I have tried quick fire photos with my camera in flash mode, but find that it takes a while to recycle, I just want to get the setup nailed before I go away in a couple of weeks.

If you set your onboard flash to commander mode and then set its power to "--" it will fire as fast as your shutter can work. Whether this gives enough light to trigger your remote strobes will depend on many unknown (to us) variables.

If they don't trigger then increase the power of the onboard flash until they do - that'll be the fastest you can get for your situation.
