Photography changed everything, from the way graphics and type were applied, to the visual appearance of the printed page. The awful realities of the civil war were brought graphically to the masses and thus may have changed history. It has been invaluable as a historical record and also used in the photographic interview. It became a documentary and communications tool in the exploration of the American west. Eadweard Muybriges’ battery of cameras captured movement in time and space and led the development of motion-picture photography.
