So Marty, I have my 700 and my 600 in front of me now. The capital M that is to the right of the squiggly arrow, I persume means that I am using it in master mode. The directly underneath that is another m that I persume once again is that I am using this flash in manual mode and I can set the compensation where I want it. So the A right below that then would be my sb600 flash and I again manually select my compensation. And then I also need to make sure that my 600 is set to display the channel and group a since that is the only other flash I have...Is all that correct? Now should I decide to have both flashes off camera and use my pop up flash as the commander, I simply switch this 700 to remote and have one set to a and one set to b and make the exposure compensation changes via in camera..Please say I'm correct and then I can sleep tonight.........Thanks Marty.
