In this chapter, the authors begin by considering photojournalism's contexts from a variety of perspectives: the cultural and social perceptions of truth to which it is still, for better or worse, held accountable; and, ultimately, how it can be defined as all of these parameters shift and change with the transformations of the contemporary media environment. They discuss the relationship between theory and practice in relation to photojournalism, including the imperative for viewers and photographers alike to commit to visual literacy, or a position of critical engagement with what the authors see. In the economy of photojournalism information, ideas, opinions, news, propaganda and commerce all interact. Their meanings are altered depending on the context in which they are printed and by the way in which they are presented. The photojournalism then, is one who makes work intended for a public audience either through editorial publication - primarily in magazines or online - or for non-governmental organizations.
