Genealogy: Archiving resolutions for film scans

Genealogy: Archiving resolutions for film scansBy Barry J. Ewell

The best resolution for archiving depends on the type and speed of the film being scanned. Faster films contain less detail than slower films and can be scanned at lower resolution. The chart below makes some recommendations based on film type and speed.

Scan Resolution Needed to Capture All Usable Detail Organized by Film Type

  • Scan Resolution: Film Type
    • 2000 DPI: Most All Films
    • 3000 DPI: Most Print Films and Slide Films 200 ISO (or faster)
    • 4000 DPI: Films of 800 ISO (or faster)
