Retouched collodion print Education in Photographic Conservation
 

Collodion print in which the emulsion layer has been damaged by water. To create the new print, the original was digitized and the digital file treated in Adobe Photoshop. The file was then converted to a negative, and the negative was printed on transparency material, then contact-printed on black and white fiber-based paper. Photo Digitalization: Kathrine Suhr and Mogens S. Koch. Photo: Collection Aalborg Historiske Museum.
