Prompt
Generate a realistic photograph of Kai Bird, a middle-aged American historian, author, and journalist, sitting at a desk with books and papers scattered around him, with a warm and introspective expression. He has short, graying hair and wears a pair of reading glasses perched on the end of his nose. In the background, a bookshelf filled with biographies and historical texts is visible, with some of his notable works, such as "American Prometheus" and "The Good Spy", prominently displayed. The style should be a realistic portrait, capturing the essence of a thoughtful and accomplished writer and historian.
