1. 3 point lighting
As the name suggests 3 point lighting contains 3 lights in different positions. There's the key light, fill
light and back light. The key light shines directly on the subject and is placed at a 45 degree angle from
the subject. It is used to illuminate the subject. The fill light also shines on the subject at a 45 degree
angle opposite the key light, it is also placed at a lower position than the key light. It fills in light into the
shaded areas to balance the key. The fill light is also not as bright as the key light. The back light shines
on the subject from behind. It is usually to one side or the other at the back of the subject. The back
light outlines the subject and separates the subject from the background.
