John Tagg is a key figure in this topic because he looked at how the 19th century changed, and the ways in which photography was part of that change. He stated that photography became an instrument of surveillance and control. He also stated that "knowledge is power, and photography a crucial form of information".
(Vicki Goldberg, „The Power of Photography‟, Abbeville Press, 1991, p. 61)
Photography has a representational task, in that the photographer, viewed as a special seer, chose to make a particular photograph. This gives authority and credibility to the image. According to Umberto Eco, the camera is like an eye.
One example of how photography can be used as evidence is the work of Lewis Hine. He worked with a labour board of child employment, and photographed the children working as a form of evidence. Hine said:
"I had to show what it was really like…The photograph has an added realism of its own…the average person believes that the camera cannot falsify."
Lewis Hine, a New York City schoolteacher and photographer, believed that a picture could tell a powerful story. He felt so strongly about the abuse of children as workers that he quit his teaching job and became an investigative photographer for the National Child Labor Committee. Hine traveled around the country photographing the working conditions of children in all types of industries. He photographed children in coal mines, in meatpacking houses, in textile mills, and in canneries. He took pictures of children working in the streets as shoe shiners, newsboys, and hawkers. In many instances he tricked his way into factories to take the pictures that factory managers did not want the public to see. He was careful to document every photograph with precise facts and figures. To obtain captions for his pictures, he interviewed the children on some pretext and then scribbled his notes with his hand hidden inside his pocket.

Other ways photography can be used as evidence:
- Surveillance
- Identification, however not always good for detection
- Mug shot
- Police photographs
Problems with photography as evidence:
- Kozloff developed the idea of the photograph as a witness with possibilities of misinterpretation, false witness and partial information
- It is time based. Barthes - "it was made there but it is here now"
- Truth
- Different meanings can be generated
Advertisements
Since the development of computer manipulation tecnology, there have been issues raised as to whether advertisements can be classed as 'truthful'. Editors can now reach into the guts of the photograph and can manipulate any part of it.
Advertising creates an atmosphere and makes the product different to others, even though it is probably very similar.
