I am completely new to the on/off camera flash photography scene and I have a couple of questions.
1. I am wondering whether if the 430EXII or the 580EXII would be the most bang for the buck and also suitable if I want to use it along with one or two Yongnuo 460II flashes? (ETTL is useless if its for off camera flash correct? Please correct me if I'm wrong.)
2. Also, would I need a TTL flash if they were strictly used for off camera only? I do not know how that works out. If I were to have a 480EXII mounted on top of a Cactus V5 on camera, and two off camera manual flashes connected to Cactus V5 receivers, how would the manual flashes know how much light to emit?
