6 different 3-point lighting

In this photo, the hair light appears to be placed to the back right of the subject, giving the model's hair more of a shiny appearance. At the same time the photographer has managed to let the exact same side of the model's face fall into shadow.

In this image, the main light gives the model's front side this sort of shining effect, while leaving the very center of her face in shadow, the hair lights catch both the left and right side of her face as well.

In this image, it is very apparent that the main light was the brightest of all, and offset slightly to the left of the model. This setup lets the right side of the face, as well as the upper right portion of the neck fall into shadow.

The main source of light seems to be coming from the right of the model (our left), and falls into shadow on the opposite side of the hood of the sweatshirt. The thing i like about this image is the ability of the photographer to work with shadows on a model with such bright, blond hair.

In this image, although the model is the same, the techniques of lighting seem ever so slightly different. The background, or hair light, is almost adding a transparent, glossy effect to the edges of the model's hair. Due to the offset placement of the main light, the model draws the majority of the light on her right (our left) side of her face, while her left side falls into shadow.

In this image, although the light is fairly dim all the way around, it is apparent that the main light is softly lighting to the left side of the model. This provides for the shadow effect given to the right side of the nose, as well as the cigarette. A very soft hair light seems to be in use on the back left of the model's head, adding a slight amount of gloss.
