I get lots of e-mail asking me to talk about tricky lighting with multiple, radio slaved flashes but the reality is that I prefer simple, one light set ups for most stuff. And most of my personal portraits are lit by only two lights and a reflector. I think there is something valuable about mastering one or two lights before even considering all the tricky and blingy lighting set ups one sees on the web or in books the raison d' étre of which is to sell glorified lighting diagrams.
One umbrella. One light. One small reflector. Old, black and white film shot.
