My first attempt at off-camera lighting. And by lack of model I took some pictures of me..

Here you can kind of see the setup/ the before: http://www.flickr.com/photos/louis-philippe/2812689039/

Main light: shoot through umbrella camera right, on the ground. I don't have any real equipement so I had to deal with whatever I could find around the house (http://www.flickr.com/photos/louis-philippe/2813539566/)
Small slave flash on background for highlight, triggered by main flash.
Reflector camera left for fill.
Plenty of running back and forth.
