Originally posted by jolepp In a sense digital is ideal for archiving as a copy of file is as perfect as the original. There are standard (jpeg) or at least documented (dng) formats that are likely to stick around (or at least be implementable) so currently keeping an archive would mean copying the files over to new media (e.g. from PATA to SATA hard drives) every 5-10 years or so to keep the stuff accessible.
I think you have it spot on. In my view digital cannot possibly decay or not be reproducible because it is simple mathematical (binary) data! It has no real physical existence (only a variable host), unlike film or other analog format.
Hence even allowing a suitable compatible media reader to be manufactured a million years into the future, to re-render it exactly as original, zero decay and guaranteed to original specs. You just need to keep the same stream of "bits" on... whatever.
I don't believe science has to date, or ever will, achieved that level of purity in exactness of replication and cross transfer to more durable medium with (analog) film images.
And Ted Turner would go and apply his version of Photoslop™ to death (TTs penchant for colourising) the stuff in the archival process anyway!
I expect if not my own digital pix, then definitely my (our) offspring's will be potentially eternal in the natural evolution process of the Internet, online storage with mega-speed on-tap retrieval will be the status quo. What could be better archiving than bit-perfect auto replication, safe, secured and off-site?
Normal backup distributed archiving principles of major networks is the assurance. The Googles of this world just do not fall over or lose data.
OnT: One reason that spurred me to post this topic was that it bought back memories of the last Kodak plant in my country closing down its Coburg Vic Au site in late 2004. It was a big thing, they'd dominated the film processing market for eons, until Digital rang the death knell.
(You probably recall the same happenings in your own countries.)
And a great pic here of an earlier Kodak Au site - before they shifted suburbs:

Hmm... so this is how the Box Brownie was assembled!

(That was the camera that imprinted 'photography' in my life~psyche from back in ankle-biter days.)
How would you like your new K-5 repaired here?
