I'm going to test my knowledge and then have people change it around on me so I learn.. but basically as I understand TTL, it is Through-The-Lens. So in terms of the flash, the exposure is adjusted when the shutter release is depressed such that the amount of flash-light needed to expose the scene correctly is fired.
On the 50DX which started all this, it didn't support the TTL way of life and only fired the flash at manual or full output ....
And my slaves (or the ones I'll buy from the Romans.. I mean, camera dealers) are fired wirelessly by sensing the light of the flash (either infra-red if you don't want a front fired flash in the shot) or by the front fire (or master) flash.
how'd I do for a guy who a week and a half ago did a friend's wedding reception with his on board little flash!!!
