Examples of 3 Point Lighting

These portraits I found below are what I consider to be good examples of 3 point lighting. They all have a strong key light, the area that is lit up the most creating a focus of that specific spot. They also all have a fill light, the light that creates a contrast on the area not being lit up by the key light; the fill light can be brightened or dimmed to create interesting dynamics is a portrait. And they all also have a back light, which is used to distinguish the image from it's background, which also creates an interesting contrast, and sets the subject into even more focus.
