Now that you have your own lights, let's talk about the basics. The basic lighting setup in film or video is called three point lighting.
The first part in three point lighting is the key light. This is the main light to illuminate your subject and your scene. the keylight is set off to the side of the camera and pointing in at a 45 degree angle.
Next is the fill light. The fill light is going to be less intense than the key and will be put facing the subject on the opposite side of the camera. this is used to fill in any shadows created by the key light.
Finally is the backlight. This is used to make your subject pop out and separate them from the background. The backlight is placed behind the subject and off to the side so it’s not shining into the lens.
