The technique comes first, followed by the subject, scene, details and aspect ratio. Paste it straight into an image model and swap in your own subject.

90° side light at the same height as the subject, half lit and half in shadow, surface texture strongly emphasized. Against a black background, an old fisherman with a deeply lined face sits in profile, light coming from the left, his wrinkles, stubble and rough skin clearly visible. 4:5, the light/shadow line on the bridge of the nose, no fill light smoothing out the shadows.

Common pitfalls

The dark side goes fully black and the information is lost.
Side light set too low gives an eerie under-light.

Parameter tips

Spell out side light at 90° at the same height as the subject; textured subjects (wrinkles, bread, fabric) love it.
