High-Contrast Monochrome Studio Portrait Prompt

Create a 1:1 high-contrast monochrome studio portrait with a half-body composition and cinematic film grain. A person with dark, swept-back hair makes direct eye contact, wearing a bright, genuine Duchenne smile. Harsh, vibrant key lighting sculpts sharp facial highlights and reveals the deep texture of a raw denim shirt with rolled sleeves. Underneath is a crisp white V-neck, paired with fitted chinos. Hands rest casually in the pockets. Set against a high-key white backdrop, the mood is relaxed and editorial, with ultra-detailed, photorealistic realism.
