By learning the different shots I wanted to implement different lighting by making the model’s seem dramatic with the dark background and to have a side shadow with the 3 point wit hair light. The last one with the red background I used a lighting showing both sides but almost looking neutral.
You’ve got your 3 point lighting switched, the first is with hair light, you can see its pointing at your model and lighting his hair/shoulders. The 2nd example the light is turned around and lighting the background.
