This look is mainly a low-key portrait setup: a dark environment, one hard key light, and careful control of spill. Based on the eye catchlights, a single undiffused light placed above and to one side of the subject can create the strong contrast and shadowy modeling seen here. In some images, a dim background light or reflector adds separation from the background.

A snoot, barn doors, flag, or gobo can help narrow the beam so the light falls mostly on the face and not the background. That controlled falloff is a big part of the look.

Subtractive lighting means removing or blocking light rather than adding more. In practice, that can mean working in a dark room, using black flags or black foam board to stop ambient or reflected light from filling the shadow side of the face, and preventing the key light from spilling onto the background. The goal is deeper, cleaner shadows.

A simple setup: place the subject in front of a plain dark background, put one hard light high and off to one side, position the camera roughly perpendicular to the light, then use black flags to keep the unlit side dark. Add a weak background light only if you need separation.
