Subject: a middle-aged man holding a professional DSLR fitted with a telephoto lens.
Pose: seated and leaning a little forward, torso turned slightly toward camera left. Both hands wrap gently around the camera body and the lens, elbows resting naturally close to his lap. He keeps the camera near his chest, protectively, in a contemplative way.
Head and gaze: head turned toward camera left, chin a little lowered, eyes looking to the side with a reflective, introspective expression.
Look: short, slightly untidy hair, naturally full on top; light stubble; a defined jawline, skin texture that shows real pores and fine lines.
Clothing: a plain black long-sleeve shirt that melts into the dark background.
Light: low-key studio setup with a strong directional key light from camera left for a dramatic chiaroscuro. Deep shadows cover half the face; bright, high-contrast highlights on the forehead, cheekbone, nose bridge and hands.
Background: entirely black, fading seamlessly into darkness.
Focus: face and hands sharp, shallow depth of field.
Camera: 85mm lens, f/2 aperture.
Style: ultra-realistic black-and-white cinematic portrait, professional studio photography, high dynamic range, detailed texture rendering, cinematic composition, a timeless artistic mood.
Output: 4:5 ratio.
