Perhaps a theory is possible from photography. (Roland Barthes) What began around 170 years ago as an expensive and elaborate pastime for a wealthy, tech-savvy elite has today become an indispensable part of all areas of life: photography. The photograph has become an essential medium of information and communication. Starting from the Linguistic Turn and the Iconic Turn, the shift towards the linguistic and the visual, Alexander Kamenski examines the communication media of text and image to highlight the relevance of photography in communication science. Both textual and visual communication are subjects of research in communication science, but they serve different functions. His main focus is on the research of Walter Benjamin, Roland Barthes, and Charles Sanders Peirce.
