【正确答案】 A

【答案解析】[听力原文] W: Hey Steve, got any plans for tonight? M: Hi, Jane. No, I don't think so. Why? Got any suggestions? W: In fact, I do. I just got two tickets to the opening of the exhibit of the reprints by Julia Emily Cameron. I would have to mention it earlier, but I was on the waiting list for these tickets and I wasn't sure I'd even get them. M: An exhibit, huh? I like such things. But I don't know who Julia... W: Emily Cameron! She was a photographer in the 1800s. She is interesting to art-historians in general and students of photography in particular because she ... how should I say, change the aesthetics for photography. M: What do you mean? W: Well, her specialty was portraits and instead of just making a factual record of details like most photographers did, you know, just capturing what a person look like in a neutral and natural way. She, like a portrait painter, was interested in capturing her subject's personality. M: Interesting! How did she do that? W: She invented a number of techniques that affect the picture. Like one of those things she did was blur images slightly by using a soft focus on the subject. That's pretty common now. Her techniques brought great influence to the later photographers. M: Yeah, she's great. Who did she photograph? W: Famous people of her day, Alfred Lord Tennyson, Henry Wadsworth Longfellow, Charles Darwin..., I don't know who else. We'll see it at the exhibition. M: You really pick my curiosity. I am going to enjoy this. W: I'll give you a call when I get the tickets. M: I bet we'll have great fun there. What is the conversation mainly about? 细节题。根据原文Emily Cameron! She was a photographer in the 1800s.及下文，可知文章讨论的是一个19世纪的摄影师Emily Cameron。
