I'm very new to flash photography.
Just recently bought a softbox kit and I'm not quite sure how to use the built-in flash on the headlight unit. The sales person tells me that it has a light sensor which could be triggered with my Canon 60d popup flash and act as a slave. I then setup my canon 60d flash control settings to wireless mode and shoot with my pop-up flash. The headlight unit flash a bright light & beep, but my photos has no light source either from my popup & the headlight unit.
Basically, I don't have an external flash and just want to use the flash of the headlight from the softbox using my canon 60d popup flash as a trigger. Is this possible? I have setup a remote flash before using an external flash as a slave and set the corresponding channel to the external flash. How can I do this on the built-in flash of the softbox? do I need to use the sync cord? Pls. help. & many thanks.
