听力原文：W: Hey Steve, got any plans for tonight? M: Hi, Jane．No, I dont 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 Margaret Cameron．I would have to mention it earlier, but I was on the waiting list for these tickets and I wasnt sure Id even get them．M: An exhibit, huh? I like such things．But I dont know who Julia…… W: Margaret 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 a factual record of details like most photographers did, you know, just capturing what a person look like in a dispassionate（平心静气的）thought of way．She, like a portrait painter, was interested in capturing her subjects personality．M: Interesting! How did she do that? W: She invented a number of techniques that affect the picture．Like one of these things she did was blur images slightly by using a soft focus on the subject．Thats pretty common now．M: Yeah, seen that．Who did she photograph? W: Famous people of her day, Alfred Lord Tennyson, Henry Wadsworth Longfellow, Charles Darwin, I dont know who else．Well see at the exhibition．M: You really pick my curiosity．I am going to enjoy this.52．
