Prompt
"Generate a realistic image of Paul Krugman, a middle-aged man with a distinguished appearance, sitting in a university setting, surrounded by books and papers, with a thoughtful expression. He should be dressed in casual academic attire, such as a button-down shirt and khaki pants. Incorporate subtle hints of his profession, such as a pen in his hand or a economics textbook nearby. The style should be photorealistic, with a muted color palette and soft lighting."
