I want to get into lighting portraits or what not. I've come across a block in finding the right equipment to create a basic light setup. For umbrellas, softboxes, and stands - I know what to do and what to get. But for the wireless setup in flashes is what I have a problem with. I'm looking into getting a regular Canon flash like a Speedlite 430EXII or a 580EXII (but more on the 430 for financial reasons). I wont be getting into hot lights or strobes just yet. I want to have a off-camera flash setup - wirelessly. I've been looking at PocketWizard so far. But I don't understand the terms of the receivers and transceivers. Anybody here who runs Canon equipment and speedlites wirelessly? Your experiences and advice would no doubt be highly valuable for me. Thank you for your time.
