The author of this Wired article,Wired 12.10: Point. Shoot. Kiss It Good-Bye, spends so much time inaccurately describing old photos as "yellowing," or merely "dusty," that he misses the huge problem of migrating all those swell digital images of his. It is a good piece on naming and organizing, but he's way too in-the-moment to consider whether he or his decendants will be able to view digital pictures Aunt Rose -- or the President -- in 50 or 100 years.
I can't say it often enough: Friends, if you want a picture to last (family portraits, Baby, graduation) take it with film and have it printed someplace nice (Richmond Camera; not CVS). Best of all, take it in black and white. The inks and papers used to print digital images have not yet been tested for longevity.
[I plan to look for a few links for y'all to back this up; gotta run, now.]
