Hi guys, It's been a while since I've even tried to use ETTL and HSS and I can't seem to find or to get either one activated. Am I missing something or is it not working right? I normally only shot using it in Auto or manual, but I would like to play with it in the other 2 modes. The instructions for it don't elaborate enough for me to get it. So if you have one or can help it would be appreciated.
