Digitization Basics

  • Capture once, use many times
    if you scan at a high resolution, you can say a copy later at lower resolution to share more easily

  • Create a faithful reproduction of the original
    you can always copy the original photo and do restoration work on the copy of the photo

  • Scan from the earliest generation practical
    details get lost as copies are made of materials

  • Technical specifications

    • Start with preferred file formats (non-proprietary is best) 

    • Balance resolution needs against file size

Organization Basics

  • Be consistent and descriptive
    • Use descriptive but concise file and folder names
    • Avoid special characters, spaces, and periods in filenames
    • Use capitals, hyphens, or underscores to delimit words
    • Use 2-digit numbers to represent 0 through 9
    • Use back-to-front formatting for dates
    • Use version numbers (or a version control system, if you generate extensive quantities/versions of files)
  • Add context (use whichever approach you will actually put in practice consistently in your life)
    • Tags
    • Metadata
    • README files
