Red backdrop studio portrait with hard shadow band

Ultra-realistic studio portrait of a young man against a bold solid red background, upper-torso framing. Subject facing slightly sideways with head turned left, eyes looking upward thoughtfully. Dramatic hard light casting a sharp horizontal shadow band across the middle of the face, partially illuminating the eyes while lower face remains in shadow. Soft curly medium-length hair silhouette visible against background. Dark shirt blending into shadow, moody cinematic contrast. Wearing black glasses. 3:4 ratio, 4K quality.
