A dramatic monochrome portrait with split lighting and deep shadows

A dramatic, high-contrast low-key portrait of a subject. The image must be in monochrome black and white. The subject is facing forward, looking directly into the camera with an intense effect. The lighting is sharp chiaroscuro/split lighting coming from one side, casting exactly half of the face and torso into absolute, pure black shadow, while clearly defining the features on the illuminated side. The subject is wearing a dark, textured button-up dress shirt that subtly emerges from the pitch-black, minimalist background. The overall mood is cinematic, mysterious, and moody. Shot on 85mm lens, photorealistic, deep shadows, fine facial details, high-end studio portrait photography.
