There are two kinds of portrait photographers: the first likes to shoot with “available light,” by which they mean “every light that’s available.” For some shooters, setting up five lights to make a portrait is just getting started. The second group prefers to use as few light sources as possible because there’s less gear to fiddle with, which translates into more time spent concentrating on the subject. Isn’t that what making a portrait is all about? Using fewer lights is less expensive, reduces setup time, and results in less weight to transport on location. But can you make a portrait with just one light?
