Tain is a series of 9 images made by loading film negatives onto cameras housed in the Musée Nicéphore Niépce in Chalon-sur-Saône. The cameras are left in the exact state in which they are kept, no focusing is done and they are put back in the same position as they are in the display case. It is therefore the camera's point of view from the museum window and, by extension, the point of view of any artefact conserved and exhibited in a museum.

These include historic darkrooms such as those designed by Jacques-Louis Mandé Daguerre and a copy of the one used by Nicéphore Niépce to create the Point de vue du Gras.
