W: Department of art design and media, can I help you?
M: Yes. I’d like some information about photography courses.
W: Let me just get the prospectus. OK, well, we do have several different courses. I’ll just run through them for you. The first is "Introducing Photography". That runs for ten weeks and it’s a foundation level course, so it’s for people just beginning in photography.
M: Right.
W: That’s on Monday evenings, from 6:30 to 9:30. Next, there’s "Black and White Photography", which is at intermediate level, so you would need some previous experience for that one. And you also have to have an interview with a tutor beforehand.
M: Sounds interesting. Which evening is it on?
W: It’s a daytime course, actually. From 2:00 to 4:30 on Tuesdays. That’s also for ten weeks.
M: That’s a pity, I work on Tuesday afternoons.
W: There’s also Landscape Photography, which is on Tuesday evenings, from 6:30 to 9:00. That’s a longer course than the others, it runs for sixteen weeks.
M: And do you need previous experience for that one?
W: Let me just check... Mm, it’s advanced level. So yes, you would, and again you’d have to be interviewed beforehand. OK? Then the only other one we do is the art of "Digital Photography".
M: I am not sure that’s for me, but which evening is it?
W: It’s a flexitime course. It’s on Wednesday, but you can do it at any time to suit you during the daytime.
M: How many weeks is that?
W: It’s up to you, really. You have to do 60 hours in all. And again, there’s an interview.
M: Right. OK. Can I just go back to the first course you mentioned? Um, what sort of things does that cover?
W: "Introducing Photography"? Let’s see what it says in the prospectus. Yes, here it is: Find out about different types of camera and camera care, learn how the camera’s controls operate, and which lens to use for different subjects, study the main elements of effective composition. That’s all it says. You could always talk to the tutor if you wanted more information.
M: It sounds a bit... basic, to be honest. What about "Landscape Photography", was that the next one?
W: Yes, that includes a field trip, where you go out with your tutor on location. But, OK, to save me reading everything out, why don’t I send you the prospectus?
M: That’d be great. Could you give me an idea of the fees?
W: I’ll just have to check... Right, "Introducing Photography", that’s ￡95. "Black and white’"s the same, I think... No, I tell a lie. It’s a bit less... actually ￡85. And then "Landscape" and "Digital", they are both ￡140.
M: I see. Thanks for your help.
