Socke said:And I can show negs to you which are brittle and discolored after some 20 years, I had a hard time scanning and restoring them some 5 years ago.
Those negs have been stored in "archival" sleeves in normal room temperature and humidity but the Kodak lab may have screwed up processing Kodak film.
From digital media I can make copies which are inistiguishable from the original, I can copy to new media and I can have several copies.
And another benefit, no picture gets lost in the mail!
And a big BUT!
I earn a living with document management systems, we use digital storage since 1993. The oldest digital archive we support is the local electricity companies asset management.
So I not only know how to maintain a digital archive, I have access to the appropriate media and recorders.
Redundancy is more important than being able to copy onto newer media.
For instance, I shoot film and store the negs and prints.
I also scan the negs into RAW data files which are separately stored on external HD's and also DVD's.
And DC Sang's point is well-taken. You may be very diligent about updating your files to new media. But many people are not. One could very well wind up in a situation where files are on obsolete media or are in unsupported older formats.
Finally, digital media does degrade over time - so I believe it is incorrect to say you can make copies that are indistiguishable from the originals. That would depend on the age of the original media. How it was stored etc.
