i have some PICT files dating back to at least 1987 that i can still
open on my Mac
<http://en.wikipedia.org/wiki/PICT>
the TIFF format, on which DNG is based, is about that old too; i believe
that one can very easily get a TIFF out of any DNG, which to me feels
like a good bet for 50 years on
(the hard part is not converting the data, it is storing the files for
decades in a way that will be continue to be accessible)
