AB Text 7
W:I like that picture you put up on the wall yesterday.
M:Oh,thank you.It's a photograph that I took on vacation last year.
W:You took it yourself?I didn't know you were a photographer.
M:Oh,yes,I've been taking pictures for years.
W:Interesting.Do you have any more of your pictures here?May I see them?
M:Yes,certainly.Some of them are just of people,just the faces of people whom I see when I'm walking around.
W:Do you let them know that you're taking pictures of them?
M:I try not to.I don't like posed pictures.I like people who are going about their business without knowing the camera's there.
W:I suppose you need a lot of equipment.How many cameras do you have?
M:Well,I have a dozen of them,but I use two of them more than the others.
