The archive of Franck Pourcel, a tirelessly active photographer, is almost inexhaustible. For this notebook published with Zoème/Filigranes, he chose to revisit it, using the experimental framework of the "Cahiers" series to bring out a different way of looking. There is continuity with the motifs found in his earlier books on factories, workers and industrial waste, but the gaze here is more distant and cold, opening onto a world that seems almost extraterrestrial.
