Help please - Nikon D70 with wireless remote SB-800 flash.

    Apologies for not doing a proper cross-post, this question is also
    asked in rec.photo before I realized my mistake....

    It took me about 20 minutes of user-guide hunting to figure out how to
    get the SB-800 to work off-camera (wireless remote) in iTTL mode, but
    I did it and the SB-800 definitely flashes and responds to EV
    compensation commands from the camera.

    What I can't get to work (and here is my question) is I was expecting
    to be able to use the built-in D70 flash together with the remote
    SB-800 and right now, it doesn't fire (well, it does, but not at any
    significant power) when the D70 is put into master mode.

    Here's what I did:
    Custom setting 19 on the D70 'Flash Mode' set to 'TTL Commander mode :
    TTL'
    SB-800 taken off-camera and set to 'REMOTE' Channel 3, Group A.
    Popup the flash on the D70, mode 'P' or 'A' and take a photo.

    Does anyone know if the built-in flash can be made to fire too
    (preferably in i-TTL mode?) - or do I need a second SB-800/SB-600 to
    mount on-camera?

    With two or more SB-800/SB-600's, the EV adjustment set on the D70 is
    going to apply to all flashes together? - or is there a way of
    individually adjusting each one?

    Also, a side-question, does anyone happen to know what method (radio
    waves? - channel settings would make you think that.. or flash
    light...) the D70 is using to communicate with the SB-800?

    Either way, wireless multi-flash is going to be a lot of fun with a
    digital SLRs that can give you instant feedback for making
    corrections. Looks like I need a couple more SB-600's and some
    flash-gels to play with...

    Thanks.

    For 2 flash i-TTL you need a second SB800/SB600. The best you can get
    with one SB800 if you want fill flash from the camera position is to set
    your built in flash to manual, and your SB800 to SU-4 mode. The SB in
    SU-4 mode probably needs to be set to manual too (there is an option for
    auto in SU-4 mode, but I think that only makes the slave (the SB800)
    start and stop in sync with the master (the built in flash) and since
    the built-in needs to be on manual that would seem to require more trial
    and error than leaving both in manual.

    The low -powered flash from the built-in flash is the method of
    communication between D70 and SB800 when the D70 is in Commander mode.
    But communication is all it does, there is not enough light to influence
    the exposure (at least while the shutter is open)
