Why are photographs powerful sources? Contextualize, one does not need to be literate to understand an image. Because photographs seemed more “factual,” they served to “authenticate” a message. Until the development of more modern technologies to change photographs easily, people tended to trust photographs more than other images, such as posters. Consider the picture of the uprising in E. Germany in 1953. Soviet tanks crushed the workers’ uprising against the communist government. One sees two men throwing rocks at a Soviet tank. The image however conveys more. Such a picture is powerful. It shows two people fighting against a tank, hopeless maybe, but their courage comes through as they seek to stop the spread of the evil of communism much like American soldiers are doing globally. Therefore, while a photograph offers a “factual image,” a photograph is not neutral. It can convey powerful emotions and meanings.
