I'm working on a school project due tomorrow and I'm running into trouble having two different 580EX's talk to each other in manual mode. When I set the power to 1/1 with one flash on master and the other on slave, it cuts down on the power of each significantly. But when I use them each individually, they're fine and shoot at their normal power. The master is hooked to the camera via a normal flash cord, and the slave is about 15' away. Any idea why the flashes are losing so much power when they work together? It almost seems as though they are combining their outputs into one normal flash. I don't want that...I want it to be completely manual. Any help would be awesome!!
Thanks |

That sounds as if somehow they were still in TTL, making up for the double power by halving the output. If all else fails, try exposure correction or flash correction? (I've never used the latter with an external flash though).

Everything's in manual mode.
Elmakias - by ratio, do you mean 1:2, 1:8, etc? Is that the same thing as you see 1/1, etc on the back of the flash? |

I couldn't figure out how to make my 580EX act as a 'master' when fired with a sync cord. Of course that was before I learned to hold the mode button for 3 seconds to get it into manual mode when acting as a slave.
1/1 is your power setting in manual mode and not your A-B balance in ETTL mode, correct?
