Ministère is a stop-motion film inspired by Hippolyte Bayard's research into a photographic process. This photographer and inventor, employed by the Ministry of Finance, spent his lunch breaks on the roof of the administration building, where he placed plaster statuettes against a black background, facing a camera obscura to obtain images that stood out in white on black paper of his own invention.

As is often the case with Bayard, the artist takes precedence over the researcher, and the plaster statuettes, simple test subjects chosen for their whiteness, multiply in increasingly baroque compositions. In the end, the images Bayard records form a kind of plaster cabinet of curiosities, whose raison d'être is only remotely its two-dimensional rendering.

The film is based on these compositions, which offer a kind of universal museum reduced to its simplest expression, by proposing the accelerated observation of the sun's course on nine objects from the Benin exhibition placed against a black background.
