The long history of visualization was marked by the invention of photography, which from the very moment of its creation was attributed the status of evidence and objective representation of reality completely intact by the photographer's perspective. The change comes with the digitization and introduction of computer processes that have made it possible to present "fake" images as real, resulting in concerns that human visual systems could no longer be relied upon as a reliable way to distinguish photographs from digital images. The first part of this thesis will include a theory that is closely related to the field of research with an emphasis on computer-generated image, photography, interconnectedness and its connection with art. The second part of the paper will be based on the research and its analysis in order to be able to draw a valid conclusion based on the conducted research in the theoretical part together with the results of the analysis of the conducted research.
