When looking at a photograph, too often a conversation starts–and, unfortunately, ends–with a statement such as, "I like it." The logical next question, "Why?", often goes unasked and unanswered. As photographers, we frequently have difficulty speaking about images because, frankly, we don't know how to think about them. And if we don't know how to think about a photograph and its "visual language"– how an image is constructed, how it works, and why it works–then, when we're behind the camera, are we really making images that best communicate our vision, our original intent? Vision–crucial as it is–is not the ultimate goal of photography; expression is the goal. And to best express ourselves, it is necessary to learn and use the grammar and vocabulary of the visual language.
