Deep Thought: Black and White Portrait on a Chair

Black-and-white, high-contrast portrait of a man seated on a simple chair in a studio. He is deep in thought, with a furrowed brow and eyes cast downward, hands resting on his lap. Use dramatic side lighting to create strong chiaroscuro: sharp shadows along the cheekbones, jawline, and nose, with soft gray tones elsewhere. Plain textured gray background. Wardrobe: dark blazer and light shirt, timeless and understated. Framing is head-and-shoulders to mid-chest in a three-quarter turn, capturing a contemplative, introspective mood. Add subtle film-grain texture and a gentle vignette; emulate classic mid-20th-century photography with crisp eyes, minimal distractions, and rich blacks and bright whites.
