Strobist Question

[Rocco]

10 and 10, or 5 and 5. The thing is that you don't really know the output, except that they're equal... The camera is going to behave as if you are using a single flash.. It won't blow it out, but it won't under expose, so distance of your various flashes will still have an impact on the photo, BUT it is going to adjust both flashes equally until it "sees" the correct exposure.

For example, you like the amount of light on group A, but group B is darker than you'd like, you can simply move group B closer to the subject. But of course, you have more flexibility by just using a different ratio.

Short answer: They're the same power, at whatever power level makes your camera think it's properly exposed.. without giving any indication of actual output. And THAT is the reason why so many strobists shoot with manual control.
