Overview: Digital photographs are produced primarily in two ways: natively born digital via a camera, or through a transformation, such as digitization. In both cases, there can be multiple versions, file formats, and file sizes for the digital photograph files. Considering in advance how to package these for digital preservation is a worthwhile activity. It will assist you with syncing files, creating instructions for your producers, and populating your digital workflows.

Packaging considerations:

  • Selection, Format, Grouping, and Metadata

Selection

  • Which digital photographs will be preserved?
  • Do you need to keep all versions of the digital photographs?
    • See your Collection Development policy

Digital Photograph File Format

  • What are the file formats for the digital photographs in your collections?
  • Are they in the preferred file formats according to the Library of Congress?

Grouping the files

  • How are the files grouped? Will you need to make changes?

  • Do you rely on filenames for grouping and accessing the digital photographs?

    • Consider using metadata such as:

      • unique identifiers that relate to specific filenames

      • structural metadata
