Can anyone recommend a book or website that will help me understand how to operate an off-camera electronic flash? I haven't had much luck finding anything more than basic descriptions of what a flash is used for.
I have a Vivitar 2000 flash and I don't know how to use it. I got it as a gift, but I've never really used it. It has three settings; one manual setting and two auto settings (green and red). I don't know what any of these settings are for. When I use this flash on my N75, the built-in flash on the camera still pops open and fires. Is that supposed to happen?
Any advice is appreciated.
Thanks,
Paul
