Prompt: A photorealistic

Prompt: A photorealistic grayscale painting of a middle-aged Asian man with short black hair, wearing a light polo shirt. Glasses rest on top of his head. He sits at a desk, holding a pen in his right hand and reading an open book with his left hand. The desk is scattered with papers; the background is softly blurred. Soft, diffused daylight from the left casts gentle shadows, creating a calm, studious mood. Close-up, shallow depth of field, high detail on fabric texture, paper grain, and skin, with grayscale tones from black to white and subtle midtones.
