Digital images, on the other hand, have fixed amounts of information. Enlargement of a digital image with ultimately show the grid structure of the image. This simply means that the pixels of the image become larger squares of color. Therefore, If you zoom in on a digital enough, you eventually will not be able to make out what the image is depicting. .
When photography was first introduced about 150 years ago, it was seen as the perfect way to document something. This is because a photograph could accurately record the subject matter. Over the years, advances in technology led to clearer, more realistic photographs. Unlike the first cameras which required a tedious setup, the modern cameras of today allow a photographer to take unrehearsed snapshots. In theory this means that the subject matter would be less composed and therefore more realistic. Photographs could now show the "truth " by exposing people in an unrehearsed manner. According to Susan Sontag (2012), "Photographs furnish evidence. Something we hear about, but doubt, seems proven when we're shown a photograph of it"" (p. 780). .
Although many news reporters and journalists claim their photographs to represent the truth, a great amount of image manipulation occurs before the picture is printed and or published. One type of manipulation that is commonly used is the actual cleaning of the film itself. This means removing scratches or other imperfections on the film. Journalists and photographers at National Geographic for example, often compensate for this. The reason they do this is to capture the subject matter as realistically as possible. Another type of image manipulation occurs when the photographer is actually taking the picture. The photographer chooses the subject matter, composes the scene of the photograph, and .
uses filters and other images techniques to change what the photograph will look like. So when one says that a photograph represents the "truth ", this is not true.
