I recently got an Alien Bees 800 W/S light, with stand and a sliver/white bounce umbrella. Due to budget constraints and certain upcoming holidays, it will be little while before I get the other two I planned on. But it seems like I should be able to do something with a single light. I've played with it a bit, but would like some more concrete ideas. Ideally I'm thinking this may be a good way to do some nudes I'd planned on. I've always wanted to try some of those single light (I assume) nudes where only a portion of the body is lit and the rest is in featureless shadow. Any hints? Tips? Ideas here?
