    A few things to try... I'm assuming your pop-up flash is what is affecting the scene in an unflattering way.

    Put a heavy diffuser over it. The other strobes should still pick up the flash without it affecting the scene as much. Or use a gobo or a reflector to keep it from directly hitting the subject at all. As long as the light is seen by the strobes they should still slave off the flash.

    You can always use a hot-shoe flash and swivel it to one side.

    Otherwise, the best solution is simply to get an infrared or radio trigger for one of the strobes. The remaining strobes will then slave off the first. (i.e. no need for a receiver for each light!)


    One other solution... ramp up the power on the strobes to far exceed the pop-up flash. Then it will not contribute enough to matter. Of course your subjects may not like the extremely bright flash...

    There are several ways - Infra red trigger, radio trigger, or a flash gun on reduced power pointed at the ceiling.

    You don't say about the set up, but for a shadow free backdrop you need several feet of separation between your subject and the backdrop; for a white background you will ideally be lighting it separately from the subject.

    A bit more info about your set-up and maybe an example would help us to help you more.

    hi guys, i was using 2 portaflash 336vm units, one to either side of me, just above head height.on full power. one was reflected off a white brolly, and the other was shooting through a white brolly. and the pop up flash was firing, to trigger the slaves on the flash heads.

    Spend 20 on this trigger and your problems will disappear! It certainly fires my 336 heads.

    All the flash units can be turned down (the pop up can be turned down to 1/125th power so that it will trigger the main lights without adding to the light from them)
