New Technique Restores Images of Old Damaged Daguerreotypes

According to TechCrunch –

Daguerreotypes – photos made with a process that used mercury vapors on an iodine-sensitized silvered plate – break down quite easily. The result is a fogged plate that, more often that not, is completely ruined by time and mistreatment. However, researchers at Western University have created a system that uses synchrotrons and “rapid-scanning micro-X-ray fluorescence imaging” to scan the plates for eight hours. The system shot an X-ray 10×10 microns thick at “an energy most sensitive to mercury absorption.” This, in turn, showed the researchers where the mercury is most prevalent, thereby bringing up the image that was lost to damage or decay.
