Photo-editing software, such as Photoshop or GIMP, has achieved popularity and notoriety in recent years. But photo manipulation is not a new phenomenon--pictures have been altered since the 1800s, when photographs were invented. Depending on the way in which it is used, photo editing can be a positive tool that merely creates enhanced photos, or a negative tool that attempts to alter reality either intentionally or unintentionally, leading to the public's distrust of photography as a source of truth.
This paper includes a brief background of photo editing and explores its various uses throughout history. It also explains some of the ways in which photos can be 'enhanced' or altered with photo editing software. It has an emphasis on the positive and negatives ways in which photo manipulation can be used, including examples of each type for analysis and comparison.
Photo editing has received a bad reputation, and with good reasons. This paper talks about not only the ways in which the technology can be abused, but also the ways it can be used to present a more accurate, useful picture.
