Our friends over at PHLEARN just released another tutorial, the goal of which was to create two completely different looks using the same model in a short amount of time. In this behind the scenes video you will learn how to set up lighting for a full length portrait as well as a headshot. They focused on creating drama for both shots using backlighting. Backlighting your subject helps to define their shape, but still leaves a lot of detail in shadow.
You can read more information about the shoot at PHLEARN, which also includes lighting diagrams (always super helpful). If you want to really get a lot more detail, you should consider their Pro Tutorials.
