The publication was released on the occasion of the presentation of the interactive installation niform in Athens (Benaki Museum) and Thessaloniki (MOMus - Thessaloniki Museum of Photography). The 'niform', as the editor notes, "is an art installation that is activated by the viewer's interaction; belongs to what we call 'practicable' works, in which the audience is invited to co-shape the work and stimulated by it". At a time when the digital image-world appears omnipotent, the interactive installation offers the opportunity for fruitful reflections on the ontology of photography, but also on its political context.
