Prompt: captures a middle-aged man standing in front of an audience in what appears to be a lecture hall. The man has graying hair and is wearing glasses. He is dressed in a casual jacket over a shirt and seems to be in the midst of speaking, with his mouth slightly open and his hands raised as if he is explaining a point or engaging with the audience. The audience, blurred in the background, consists of a large group of people, likely students, who are facing the speaker, indicating that he is the focus of their attention. The setting is an auditorium with tiered seating, and the warm lighting casts a soft glow on the scene, highlighting the speaker and creating an intimate atmosphere despite the size of the audience. The overall impression is of an academic or professional event, such as a university lecture or conference presentation
