    Current Equipment: Canon Digital Rebel XT, 580EX Flash

    Ok here is the deal.... have kids line up against backdrop and bam
    shadow that i don't like...for kicks lets say I have decided to
    purchase either another 580EX (this time II) or a 430EX II. After
    studying what I would need I thought maybe the cord that is only 3
    feet long.....but it appears to me that 1 end of the cord goes on the
    camera where my current 580EX goes; therefore the cord would only be
    good for 1 flash but away from the camera. Therefore after more
    research....AHhhhh the STE-2 wireless transmitter is the answer (or is
    it....) put this on the camera buy another flash and bam now I can
    have both flashes working. However kept on fighting myself......"200
    bucks just for a transmitter let alone buying another flash, ehhh".

    Just tonight, yes I took a gander at my current 580EX book
    manual......it would appear (and this is my MAIN QUESTION) that
    somehow, haven't figured out the details yet, this 580EX can by
    itself, without the $200.00 transmitter, act as a "master" and it
    would be on the camera and somehow if I had another flash in slave
    mode, my current 580EX could make the other flash go off.

    Therefore I'm starting to think to get rid of the shadow behind the
    children, I would only need to purchase another 430EX or 580EX (no
    wireless transmitter or cords). Am I reading the manual correctly?
    Thanks.

    Basically, you're right. On the "back" side of the flash (the side
    that faces you) there's a switch towards the bottom. IIRC, it reads
    "off" to the left, "master" to the middle, and "slave" to the right.
    Put the flash on top of the camera to "master" and the other flash to
    "slave". Then make sure they are both on the same channel. It's a IR
    system so the slave has to be able to "see" the master but you can
    point it right at the master and then swivel the flash towards the
    subject. You can also use the master to control the relative output
    of the slave by turning the power of either one down in increments.

    It works pretty well. You have to remember to give time for both
    flashes to recycle between shots.

    Also, move the kids away from the backdrop and it's do a lot to
    control the shadows.

    Finally, another alternative is to use the cable and get a "wedding
    arm" to move the flash a few more inches above the camera. It cures
    red-eye and does a lot to control the shadows because they are blocked
    by the subject.

    Good luck with it.

    The answer is yes, you need no synch cords or transmitors to pop off two
    Canon Flashes.

    Yep, that's exactly how it works and the ability to work as an ETTL
    remote master is one of the differences between the 500 series and the
    400 series Canon flashes.

    Yes you are reading it properly.

    I might suggest that if you have a white ceiling you might do
    best by pointing the flash at the ceiling about half way to the
    subjects and using the white defuser. As previously noted, moving the
    flash from the camera helps.

    Can't the Rebel's built-in flash act as a master to trigger the 580EX?

    The 5xxEX flashes can serve as masters for wireless flash.

    Not needed. Use the extension cord for your 580EX, set it
    to Master, use the slave mode on the 430EX (or 420EX or 550EX
    or 580EX) and put it on group B (Why? Read the link below!).
    No need for an STE-2, unless you need more distance than a (maybe
    different) flash cord can give you.

    Go read http://photonotes.org/articles/eos-flash/ a couple
    times till you really understand what happens. Flash is
    *not* intuitive, you've got to *learn* it the hard way.
