The introduction of paper photography in the mid-1850s reduced the cost of photographs, further democratizing the process. Photographers were able to capture ordinary men and women in the studio, at home and at work.
Photography was used not only by professional portraitists, but also by artists, scientists, adventurers and, eventually, by the amateur public. Early paper photography was used to capture the world outside of the studio: from the battlefields of the Civil War to the U.S. geological western landscape surveys.
The camera also played a key role in the rise of mass modern communication and the cult of celebrity. The practical applications for photography were endless; the camera was used to record technological achievements, sociological realities and scientific discoveries.
