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.
