I also am very interested in this use of slave flash. I would have expected the TTL functions to operate normally on the camera for not only the onboard or external mounted flash but also for the slave flash. If you set the slave for less then you expect to need 1/16 etc, then the on camera flash would make up the difference wouldn't it? It would read the total provided light from both flashes via TTL and provide the necessary amount on the on camera flash to provide correct exposure.
I'm not saying I know this to be true, but rather pose this as a question. Dave > No TTL that way. You must manually set flash output and probably > meter manually.
