The July 18 edition of the Weekly Genealogist that the NEHGS emails to members had a link to a Science News article on using particle accelerators to restore completely unreadable, tarnished daguerrotypes. Here is a link to the actual journal article in Scientific Reports, published June 22nd. It shows the before and after pictures and has the scientific details about how the process worked. These were images from the National Gallery of Canada. There is also a downloadable at the very end, labeled "Supplementary Material," with a little bit more. No word on when or if this is something other curators of photography exhibits would be able to access and restore these images from the 1840s-1860s.
