I am a beginning wedding photographer using off camera flash for the first time during a wedding reception. It will be outdoors in a big white tent. I plan to mount my Canon 600EX II-RT on-camera to use for candids, photos of guests, etc. and have my Canon 430EX-II on a stand by the dance floor for toasts, first dance, etc.
My question is, with this setup do I need a pocketwizard or some sort of transceiver attached to the 430EX-II, or if it is set up as a slave will it fire with the 600EX II-RT alone? If I do need a transceiver, do I need one for the 600 as well?
Apologies for the novice question, as this is my first time using a two-speedlite setup.
