Three Point Lighting Technique

Before any Lighting: 

Here's a shot of Tre Paige without the key light, fill light, and backlight. The only lights that were on were the ones in the classroom. 

Key Light: 

Here's Tre Paige with the key light and this photo is without the lights in the classroom. 

The key light is the first and usually most important light that a photographer, cinematographer, lighting cameraman, or other scene composer will use in a lighting setup. The purpose of the key light is to highlight the form and dimension of the subject.

Fill Light:
Here's a photo of Tre Paige with the key light and fill light on. As you can see that the photo is a clearer. In television, film, stage, or photographic lighting, a fill light may be used to reduce the contrast of a scene to match the dynamic range of the recording media and record the same amount of detail typically seen by eye in average lighting and considered normal.

Back Light: 
Here's a photo of Tre Paige with the key light, fill light, and back light. You can see the difference in this photo because all of the lights are on and this gives the photo perfect lighting. A backlight is a form of illumination used in (LCDs). As LCDs do not produce light by themselves (CRT) displays), they need illumination or a special light source to produce a visible image. Backlights illuminate the LCD from the side or back of the display panel, unlike front lights, which are placed in front of the LCD. 

Wide Shot: 
In this shot you're able to see every light and the angles that these lights were placed in. Each light had a different effect in every picture.
