You do not always need many lights. Sometimes, one light is enough:

That is just one studio light, fired through a pocketwizard (but I could have used a cable) – and a reflector on the other side. This leads to this:

Yes, of course a background light, hairlight,and so on, would give me more control.

But we should all be aware that this amount of lighting is sometimes neither possible nor practical. And one light plus a reflector can give you nice light.
