What are the speakers doing as the conversation begins?

M: Did you take these pictures? They are very good.
W: Yes, I think they turned out very well too. I like to bring my camera with me wherever I go. That’ s way if I see something attractive I can take a picture of it.
M: Carrying a big camera around is too much trouble for me.
W: My camera is really small enough. Here let me show yon.
M: That is a compact camera. But you must know a lot about photography to get such professional looking results.
W: Not necessarily. This camera is simple to work. It has an automatic focus. I don’t even have to worry about focusing.
M: That’s what I need. When I take pictures, they usually come out blurry because I don’t adjust the lenses properly. And I hate photos that are out of focus. Is a camera like yours very expensive?
W: Less than you’d expect. Why don’t you check the prices that Head Fields demonstrates? This model was on sale there last week.
M: I think I will. It certainly won’t hurt to take a look.
