    Yes. Slave function. Most studio flash units and some speedlights have an optical sensor that detects a flash in the vicinity, and fires its flash at the same time as the triggering flash. The triggering flash can be any electronic flash, such as a speedlight, another studio strobe, or the built-in flash on (my) camera. ( I remember yours does not have a built-in flash)

    So no RF trigger or cable needed. The main drawback is the lack of convenience in setting the flash power remotely. Your RF trigger might do that, or a zone controller, but with using the optical slave function, you have to set the power level manually.

    One other drawback with optical slaves, if used with a modern TTL flash, they fire on the preflash, and have nothing left when the main flash fires & the image is taken.

    With a photo booth type setting the flashes can be run repeatedly in manual mode once the correct settings are determined, so an optical slave should work well. I think they might work out cheaper than a splitter & physical wiring too!

    "Cheapest Possible" How about one of the new flashlights? They have a lot of white light from a couple of small batteries. I don't know what "color" but it seems very white???

    UPDATE - here's the chart.
