Night Kitchen
The fridge opens; half his face stays in the dark.
The setup
The single motivated source is the open fridge. On set, a soft, cool LED panel hidden inside it does the work. A black solid on the right kills any bounce, so the face splits in two. The warm pendant in the background adds depth and colour contrast.
On a budget
A real fridge light is too weak for most cameras: put a small battery LED panel inside and hang a black cloth on the opposite side. Any warm household bulb works for the lamp behind.
