But this argument holds for film too, one burst pipe, flood or fire and poof! Those somewhat flammable negs (still better than nitrocellulose) are ashes or sodden beyond recovery. How many here make duplicates of every roll or sheet and store them in another place?
I just think this argument is wielded rhetorically more than anything else. It has merit but its overstated.
True... but how many house fires have you suffered versus storage media failures in your lifetime?
But yes, true archival does mean multiple copies in multiple places, regardless of the format. And maybe it's time for a bigger fireproof box for our important docs ;-)
The main reason I keep my negatives is because I may want to re-scan them if better digitizing methods become more available / affordable. Some of my early slides have been digitized a third time.
This. A lot of my early stuff was scanned with a circa-2001 Plustek that I think was 1800dpi - all I could afford back then. Seemed OK at the time, B&W and slide was fine but manually inverting colour negs in Photoshop 5.5 was, ah, a little hit and miss.
Going through and rescanning at 20MP+ with a decent DSLR/macro-bellows setup, and the joys of Negative Lab Pro... well it's like seeing the images anew all over again.
I do tend to agree with another poster though, we're probably not going to see the same kind of improvement again in another 20 years. Only so much detail you can pull out of a typical 35mm frame... medium/large format is a different matter...
