Curt Y Jan 21, 2014 5:17 PM (in response to Spoot51)Question: Do you think the scan you make today can be read by a computer 40 years in the future? Or even 14 years? Also, digital copies on disks don't last forever either.

bob frost Jan 22, 2014 2:02 AM (in response to Spoot51)I'm busy rephotographing my old Kodachromes with a 60mm macro lens and my D800E, using a cheap screw-on SRB-Griturn holder. The results are as good or better than my old Nikon 5000 scanner which bit the dust some time ago, and having raw files allows far better processing than the scanner software did.

Yup, that's the way to do it. My experience exactly. The Micro-Nikkor 60mm f/2.8 is outstandingly sharp, and - equally important - flat field. It's the perfect lens for this.
Don't use a flatbed scanner if image quality is important. Even the best Canon and Epson scanners have nominal resolutions that are way beyond what they can really resolve optically, so those numbers don't mean much. And there is usually very bad chromatic aberration (color fringing). With my Epson I found the effective resolution to be around 4000 pixels long side, for a 35mm frame, even though the scanner would natively deliver 8000. And I still had to deal with the fringing (a nightmare).

Spoot51 Jan 22, 2014 5:23 AM (in response to twenty_one)Thanks, Curt Y and Bob Frost! That's a method I never knew about and your answers make sense. I do have a macro for my Canon 6D and am going to try it. Of course
today's technology will change, but I view the preservation in future using whatever method will be my grand kid's problem, assuming their generation wants to archive what I have.
