On a Mars colony in the year 2145, an officer in a rebel militia discovers that his sister, who was abducted a dozen years before, is still alive and has been raised as a soldier whose goal is to bring about the destruction of her brother s faction.

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.
