I'm going to interview a photographer who takes portraits. What questions should I ask?

Of course, the interview photographer should ask some professional questions, including: portrait shooting skills, lighting, background blur, lens use, how to shoot the characteristics and expressions of portraits and so on. Don't ask questions that make the other person feel retarded or bored, mainly from the professional point of view, and the most important thing is to make the interviewee realize that you know or are interested in photography.
