The article discusses the question of photography as a historical source, in particular understood as an iconographic source. It touches the problem of historical iconography as well as unwritten sources in history. Research on photographs aims to understand them as a specific type of iconographic sources, or indeed sources of a new type defined as visual sources. Theoretical refections on the nature of photography (according to J. Berger, R. Barthes, M. Michalowska), semiotic theory (according to Ch. S. Peirce), the concept of representation and presentation were used. Photographs are presented from various points of view.
