A majority of today’s visitors to the Auschwitz memorial site take photos to document their stay. By calling attention to visitors’ photography on site, this article investigates the role of visual perception and visual techniques of memory for visits to memorial sites and empirically discusses the significance of historical imagination in linking the past with the present.

The strongest emotional impulse expressed in amateur photography on site is the feeling of the sublime, which supports the need to promote moral ideas like freedom or justice in the face of the past.

Single images function within this as "storyboards" because of their strong narrative as well as mnemonic quality.
