How did Adobe Photoshop challenge ideas about whether photographs show the truth?

Adobe Photoshop challenged the long-held assumption that photographs provide an objective record of reality, often summarized by the erroneous cliché that "the camera does not lie". By providing tools that allowed users to easily alter the structure and contents of an image, the software fundamentally questioned the medium's "truth value" and documentary authority.12

While photography has always involved creative choices—such as vantage point, lighting, and darkroom techniques—Photoshop enabled a level of seamless manipulation that went far beyond traditional methods. This capability led to significant ethical concerns, particularly in journalism, where the digital alteration of news photographs resulted in public outcry and the establishment of strict journalistic codes of ethics to regulate image integrity.12

Ultimately, the rise of digital imaging forced a reevaluation of the photograph's role as a witness to truth. While some photographers embraced the creative possibilities of this "mutable" medium, others reacted by returning to 19th-century analog processes to reclaim a sense of physical authenticity.1
