Re: filmscanners: Rescans and archiving

Hi Eric,

This is a dilemma you and others will be facing each time there is a 
technological improvement in image acquisition and storage.

Is it worth rebuilding your basement when you put an addition on your 
home?  Well, that depends...  will it support the extra weight?  Is it 
crumbling?  Could it be designed better a second time around?

Verbatim disks are supposed to be fairly stable.  No one knows for sure 
which will last the longest, because they all are being testing with 
accelerated aging models, which do not reflect real world conditions.

Are the scans coming from your new scanner so improved that it worth 
your time to rescan them?  Certainly, it is likely the 2900 dpi the 
Nikon provides is closer to 2900 dpi than the 2400 dpi reported by the 
HP scanner, so its more likely a 30-40% increase rather than 20%.

My approach to this would be to ask why you archived them on disk to 
begin with.  Is it to protect the images from loss due to the degrading 
of the film over the next 20-30 years?  Is it so you can print from the 

If it is for printing, I'd only rescan those images that you plan on 
reprinting, especially in a larger format.  If you are trying to protect 
the images from loss due to film damage, either make sure the film is 
well stored and can be scanned at a later date when needed, (hey, you 
might have a 4000 dpi or 6000 dpi scanner next time), or if you don't 
think the film will survive, scan it now with the best scanner you can 
afford, and put it on the best rated disks for longevity.

Personally, I trust my film to maintain most of its integrity for many 
years to come, so I'm not panicking to get everything on CD-R.
