Black and white monochrome male portrait, Nano Banana

Create a high-contrast black-and-white cinematic portrait of a man around 30 years old. He has natural facial proportions, strong jawline, expressive eyes, defined cheekbones, and realistic skin texture with visible pores and fine details. His expression is serious, confident, and introspective, looking directly into the camera. Pose him in a thoughtful pose with one hand resting gently on his chin, head slightly angled toward the camera. His hair should look natural with visible strand detail, and if facial hair is present, it should appear well-defined and realistic. Use low-key studio lighting with a key light slightly above eye level from the viewer's left, creating sculpted highlights on the forehead, nose bridge, cheekbones, and beard texture, with deep but detailed shadows. Add very subtle rim light along the hair and shoulders for separation. Background should be pure black with no texture. Composition is a tight head-and-shoulders portrait (4:5) with sharp focus on the eyes and shallow depth of field. Style: cinematic fine-art monochrome photography, ultra-realistic, editorial studio quality, 8K resolution, sharp micro-details.
