The photographic archive contains the documentation relating to furniture, paintings, personal items and decorated surfaces of historical and artistic interest - often accompanied by images of the exteriors and interiors - of monuments and museums in Rome and Lazio included in the period from the Middle Ages to the nineteenth century.
The Archive holds about 300,000 negatives on black and white film, 320,000 positives on black and white paper, 70,000 colour slides, more than 2000 negatives on glass plates. This huge heritage is for the most part in the form of photographic prints in b/w, 18x24cm format, on cards with a short information caption, inserted in drawers with topographic and alphabetical order in the case of the territory of the city of Rome, by inventory of the works in the case of museums. As for the colour documentation, this consists of slides of all formats (24x36mm, 6x6cm, 10x12cm, 13x18cm, 20x25 cm), stored in special albums according to the same criteria as the black and white photographs.
This analogue heritage is on its way to becoming historical, as it is the result of shots relating to cataloguing, restorations, exhibitions in the area and in museums conducted between the seventies of the twentieth century and the early twenty-first century and above all of a technology that is no longer in use.
Added to this there is the digital photographic documentation, the result of photographic campaigns carried out since the 2000s, as well as the progressive acquisition in various definitions of the analogue photographic material. The Archive holds about 15,000 files from digital photographic campaigns and about 10,000 acquisitions from colour slides.
The current Archive is divided into three main sections, flanked by minor sectors relating to exhibitions, constraints, diagnostic investigations and documentation from the technical office:
This core contains photographs of furniture, paintings, personal items, etc. relating to churches, palaces, villas, entities, taken during the course of cataloguing campaigns, documentation for exhibitions and studies conducted from 1970 until about 2000.
