Split portrait lighting

A dramatic studio portrait of an adult woman with slicked-back dark hair facing the lens as one hard lateral key divides her face along the nose ridge, half lit and half near-black. No letters, words, signs or logos anywhere in the image. A real photograph, a studio portrait made on a full-frame digital sensor at 85mm and f/4, with fine low-noise grain and natural skin texture. A single hard lateral key at ninety degrees divides the face along the nose ridge: the lit half holds full material detail while the shadow half is unfilled and falls to near black. A clean terminator runs along brow and nose, with crisp microcontrast on the lit side and neutral, true-to-life color.
