As I understand this, the only way I can avoid pre-flash that is scaring the dickens out of my little birds before they are captured, I need to use manual, M. I've previously tried to shut off pre-flash without success and believe it's necessary for ETTL to function, so I don't want to use ETTL.
The 2 flashes are being used for fill at reduced power and 20mm setting. They are out of reach once I'm set up. I'm using the 6D to control the master/slave via a hot shoe cable. The problem is that while I can configure the master for M and RT with the master as A (and slave as B), I can't make the slave operate in M, the mode button is inoperative.
My goal is simply to not have pre-flash and to remotely balance the two fill flashes from my camera. 6D set to M. Help please.
