What is a 3 point lighting system? As the name implies, it is a system made up of 3 light sources, positioned over the person to be recorded. Each of these lights is given a specific name: the key light, the fill light, and the backlight.
The key light - It is the most important light of the three, located in front of the person to be recorded. It is she who defines the basic lighting of the scene. Most of the time, direct and concentrated light is used here.
The fill light - It is the light that is located next to the person being recorded. Its basic purpose is to soften shadows caused on the person's face (eyes, nose and neck) by the main light and to fill in the voids that cause those shadows, hence its name, fill.
The backlight - It is the light that is located behind the person being recorded. It has the basic purpose of shaping her face by detaching it from the backdrop and highlighting the distance it is in relation to the background. After positioning the main light, the backlight is the second light to be adjusted. It is placed diametrically opposite the key light.
