"200-Year-Old Photos Rediscovered After Being Lost for Decades"
Researchers at Western University in Canada have developed a novel imaging technique using synchrotron light to retrieve images from badly tarnished 19th century daguerreotypes, a form of early photography. The process involves using narrow beams of X-ray radiation to reveal hidden details in corroded images, bringing to light portraits and historical artifacts that seemed lost forever. The technique has potential implications for scholars studying history and could also be applied to study other historic artifacts or fossils with severe surface deterioration, as well as for scientists studying corrosion on materials.
