One of my workshop attendees is using some of the very simple (yet elegant) lighting techniques. I am a huge believer in light as a substantive property that is malleable and controllable. Light is photography's most important subject.
This image is so well lit that it is hard to imagine that it was lit with only a couple of work lights and a shower curtain. But when you know how to light, the tools become simple to use. And you will find that manipulating light doesn't require a ton of money, just a lot of practice and creativity.
