"In this text, Keith F. Davis examines photography's social history and aesthetic development in an era of rapid national growth. He demonstrates how key themes and genres - including the business of daguerreian portraiture, the markets for Civil War images, and the art of Western landscape photography - reflected the concerns and values of nineteenth-century society. Photographers of this era expressed a new national consciousness while, at the same time, helping to shape it. They also explored the visual language of a radically new medium, laying the foundation for all of photography's subsequent history."--Jacket.
