AIC-PMG Winter Meeting 2025

Fifty years is a long time in the relatively short history of photograph conservation. This presentation begins with the rediscovery of the matte collodion process and the then current belief that most issues seen in photograph prints were caused by poor fixing or washing. Since then, much has been experienced; and this will be this conservator’s focus – which immersion techniques have gone well, when have there been issues, and how can potential problems be identified ahead of time. While gelatin photographs make up the majority of examples, other processes will be included other processes will be included as well.
