Photographs
Pros: Photographs are good tools to make or emphasize a point or to explain a topic. For example, when explaining the shanty-towns in a third word country it would be beneficial to show a picture of one so the reader can have a better understanding of how those people live. A photograph is also good to use when the actual object cannot be viewed. For example, in a health class learning about cocaine, the teacher cannot bring in cocaine to show the class because that would be illegal, but the teacher could show a picture of cocaine to the class. Using local photos can also help emphasize how your topic is important in the audience's area.[7]
Cons: If the photograph is too small it just becomes a distraction. Enlarging photographs can be expensive if not using a power point or other viewing device.
