The idea of an art world forms the backbone of my analysis. "Art world" is commonly used by writers on the arts in a loose and metaphoric way, mostly… - Howard S. Becker

For any picture, ask yourself what question or questions it might be answering. Since the picture could answer many, questions, we can decide what question we are interested in. The picture will, of course, suggest that some questions are likely to find answers in it. For instance, Owens's pictures of pantries and refrigerators clearly suggest that they will answer questions about what kinds of food the inhabitants of the houses store and presumably eat, while other pictures in Suburbia suggest that they will answer other questions about the housekeeping arrangements of these people.

Photographers learn to interpret photographs in that technical way because they want to understand and use that ‘language’ themselves (just as musicians learn a more technical musical language than the layman needs). Social scientists who want to work with visual materials will have to learn to approach them in this more studious and time-consuming way

Imagine you are doing a woodworking project, perhaps making a table. Fortunately, you needn't make all the parts yourself. Some are standard sizes and shapes - lengths of two by four, for instance - available at any lumberyard. Some have already been designed and made by other people - drawer pulls and turned legs. All you have to do is fit them into the places you left for them, knowing they were available. You want to make an argument instead of a table. You have created some of the argument yourself, perhaps on the basis of new data or information you have collected. But you needn't invent the whole thing. Other people have worked on your problems or problems related to it, and have made some of the pieces you need. You just have to fit them in where they belong. Like the woodworker, you leave space, when you make your portion of the argument, for the other parts you know you can get. You do that, that is, if you know that they are there to use. And that's one good reason to know the literature: so that you will know the pieces are available and not waste time doing what has already been done.
