Dal dagherrotipo al pixel

Breve storia della fotografia applicata ai beni librari e archivistici

Incontri e convegni

con l'intervento di Walter Biondani e Eleonora Piras (Laboratorio di digitalizzazione dell'Archivio provinciale) e di Marino Degasperi (Ufficio beni storico-artistici - Archivio fotografico storico).

Il laboratorio di digitalizzazione dell'ufficio Beni archivistici, librari e Archivio provinciale è attivo dal 2002. Le attività svolte spaziano dalla digitalizzazione di microfilm all'acquisizione diretta di materiale originale, tramite scanner appositi e fotocamere digitali.

I tecnici del laboratorio ripercorreranno brevemente la storia della fotografia, illustrando l'evoluzione delle tecniche e delle tecnologie messe in atto fin dai tempi di Daguerre per riprodurre documenti, manoscritti, mappe e opere d'arte.

Sarà inoltre possibile, grazie al personale dell'Archivio fotografico storico della Soprintendenza, osservare dal vero antiche stampe e lastre fotografiche conservate presso l'archivio stesso.

Seguirà una visita al laboratorio di digitalizzazione.

Riprendono giovedì 23 febbraio gli apprezzati "Incontri del giovedì in Archivio provinciale"
