The daguerreotype is the first publicly available photographic process, creating a single, unique image on a silver-coated plate and giving us a glimpse at such historic figures as Abraham Lincoln and even John Quincy Adams. But they're extremely fragile, with air and moisture threatening to erase these images forever. At the National Portrait Gallery, photographs conservator Christina Finlayson walks Adam Savage through the delicate and precise process of preserving daguerreotypes for posterity.
