David Lynch turns his camera on Idem, a lithography workshop tucked into the Montparnasse district of Paris, built in 1880 by printer Emile Dufrenoy to house his presses. The film follows the studio's craftsmen as they ink stones, run heavy manual presses, and pull prints for the artists who still come to Idem specifically because the process is slow and physical rather than digital. Lynch, who has worked there himself, lingers on the mechanics: the grain of the limestone blocks, the smell of solvent, the pressure needed to transfer an image without tearing the paper. There is little narration; the sound is mostly the studio itself, rollers and presses and quiet conversation in French. The film treats lithography as a disappearing craft worth preserving on its own terms, not as a lesson in art history, and Lynch's affection for the machinery and the people running it comes through in how much time he gives them simply to work.
