Black and white cinematic studio portrait, Nano Banana Pro

Create a high-contrast black-and-white cinematic portrait of a British woman around 25 years old with natural facial proportions, expressive eyes, defined cheekbones, and realistic skin texture with visible pores. Her expression is calm, confident, and introspective, looking directly at the camera. She is posed thoughtfully with one hand gently resting on her chin, head slightly angled. Her hair is shoulder-length with natural volume and visible strand detail. 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, and cheekbones with deep but detailed shadows. Add a subtle rim light on the hair and shoulders for separation. Background is pure black with no texture. Tight head-and-shoulders composition (4:5), sharp focus on the eyes with shallow depth of field. Style: cinematic fine-art monochrome photography, ultra-realistic, editorial studio quality, high detail.
