Hey! I really want to experiment with off camera lighting for an upcoming wedding. I have some cactus triggers, but they suck, so I'd really like to buy some pocket wizards. However, I am clueless about what to buy and how to work them! I have two cameras (40d and 50d) and two flashes (430ex and 580exII). My husband and I each shoot with a separate camera and flash. I'll be honest, I really don't know the difference between a receiver and a transmitter, so I need a lot of help. I would like for us each to set up a flash on a tripod during the reception, so that we would NOT have a flash directly mounted to the camera. What would I need to buy in order to do that? Two receivers and two transmitters? Also, what if I wanted to sync one camera to set off both flashes at the same time. Would that be possible? How about if I wanted to sync both cameras to set off both flashes whenever either camera was fired. Would that be possible too? I know I have a lot of questions! I am very clueless on this topic so any help would be greatly appreciated! Thanks!
