The study focused on the materials from the Luigi Ciminaghi collection, for a detailed analysis of the challenges of preservation (environments and materials).

Microclimatic conditions were monitored over a twelve-month period with the use of data loggers linked to the eClimateNotebook® software (Image Permanence Institute), with the aim of increasing preservation systems with a view to criteria of environmental sustainability.

The work, which was carried out in collaboration with the restorer Silvia Berselli, provided for the reconditioning of the material relative to each shoot (negatives, contact sheets, slides, and enlargements of various sizes) using PAT (Photographic Activity Test, ISO 18916:2007) certified containers and materials, as well as the sampling of photographs to monitor their state of preservation.

Photographic material and conservation methods for film and prints were also analysed by the laboratory centre, a process that saw the participation of students from the Photo Cataloguing and New Media course at the I-Crea Academy – Fondazione ITS, Milan.
