Djahânnâma Publishing focuses mainly on publishing photography :
printing books and producing exhibitions.

Men pass through time with tragic rapidity ; things survive more stubbornly ; time, pursuing itself in its ­perpetual cycle, forgets everything.
  But the existence of things can be expanded thanks to the art which thus becomes, at the same time, souvenir and symbol, a memorial to man’s fragile existence. In resisting the passing of time, photography is a privileged art insofar as it is by choice both fixity and timelessness. […] Time is frozen within the photographic image and in the coincidence of the event as an unrepeatable moment in eternity, a moment exempt from the corruption of death. It is the realm of memory, which encompasses the instantaneous and the eternal, revealing itself as the essence of photographic art.
- Tiziana de Meis and Vito Volpe, writing about Pier Paolo Pasolini
