Im kinda new to the whole off camera flash thing. I want to get into flash photography because a lot of the photos that I take are of BMX, but I don't know what I need to buy! I have a Rebel T2 camera body, and some old flash that I found in my basement (no clue who makes it, only thing written on it is TA-85). What type of setup do I need to have to make 2 or so flashes fire off of my camera? I have looked at getting pocketwizards, but they are pretty expensive and I am on a limited budget. Canon flashes are way too expensive for what I would be using them for. Maybe a couple Vivitar or Sunpak flashes? And should I hook the flashes up to my camera using wire or do it remotely? Again, I am new to flash photography, so please explain whatever I need to know. Any and all help is greatly appreciated.
