The Archivio Fotografico Elio Conti consists of approximately 3000 photographs taken by Prof. Elio Conti (1925-1986) from the early 1960s to the mid-1980s. The objective of these photographic campaigns was a survey of the areas of the Florentine countryside that were the object of study and research for the publication of the volumes La formazione della struttura agraria moderna nel contado fiorentino (1965). In 2014, the photographic archive was donated by the family to the Istituto Storico Italiano per il Medioevo (ISIME). Before proceeding with the donation, the heirs commissioned the Associazione di Studi Storici 'Elio Conti' (ASSTOR) to digitise the entire photographic archive, with the aim of creating a website open to the free use of the wider public. In 2022, thanks to funding from the University of Siena, ASSTOR started to put the photographs online. The illustration of the methodologies and tools of digitisation, geolocation and metadataisation that have presided over this work, as well as the ways in which the photographic archive can be used online, constitute the subject of this report.
