Three-Point Lighting is when the light is positioned in three different positions so the subject can be illuminated as desired.
The background light is the one that is pointed towards the back drop to make the subject stand out.
The key light is the main light used in the photo which points towards the subject and provides the brightest lighting.
The fill light reflects the light from the key light to create shadows on the subject but also maintaining a balance so the subject isn’t to dark.
