Create a restrained fine-art portrait of a fictional 58-year-old male symphony conductor with salt-and-pepper curls and a thoughtful expression. Seat him on a plain wooden chair in an empty rehearsal hall, wearing a dark unbranded jacket over a black shirt. Compose a vertical 3:4 chest-up image with an 85 mm portrait lens, eyes just above center and one hand resting naturally on the chair arm; a slender baton rests on a separate tabletop. A narrow softbox at camera left creates sculptural side light with gentle shadow detail; the background fades into smoky brown acoustic timber. Show wrinkles, beard stubble, jacket weave and honest asymmetry. Warm muted monochrome with precise eye focus and subtle film grain. This is an original character, not a celebrity likeness. No conducting gesture, text, logos, oversized hands, extra limbs or plastic skin; produce a single finished photographic bitmap.
