The importance of lighting direction for tone
Lighting is really what makes a photograph. And as a subset of lighting in general is directional lighting. The direction your light source comes from makes a big difference, especially in the tone of a photo. So here for you I have a multi-directional example of how light can look. I also did a couple from further and further behind the head to see how the light wraps around to the face.
These are shot with a single strobe in a variety of directions, but a consistent distance from the face. There is also a Canon 580EX II Flash
