The technical process of creating digital surrogates of physical objects by photographic capture, flatbed or large‑format scanning, or other imaging methods, accompanied by descriptive and technical metadata, intended to improve access, enable documentation, and support preservation workflows while recognizing that a surrogate is not equivalent to the original physical object.

Principle

Digitization aims to produce faithful, reproducible representations by controlling capture resolution, color accuracy, lighting, scale and metadata; the utility of a digital surrogate depends on capture fidelity, file formats, and associated metadata as well as ongoing digital stewardship.

Demonstration

Illustrative scenario: An archive photographs manuscripts using calibrated lighting and a color target, captures at a high resolution saved in a lossless format, and records creation metadata and provenance. Result: researchers can consult the surrogate remotely, handling of originals is reduced, and a preservation master is available for reuse and derivative access copies.

Misapplication

Assuming digitization equals preservation — for example, discarding originals after low‑quality capture or treating a low‑resolution web image as a preservation surrogate. The error is conflating access copies with preservation masters and overlooking metadata and storage integrity.

Consequence

Proper digitization increases access, reduces handling risk to originals, documents condition at capture time and enables downstream uses (research, reproduction); poorly executed digitization or inadequate digital preservation creates misleading or unusable surrogates and imposes continued costs for re-digitization and data management.

Reversal

Digitization may be inappropriate or insufficient when three‑dimensional texture, translucency, material properties or multispectral information are essential and cannot be captured by the chosen method, or when legal, ethical or cultural restrictions prohibit creation or dissemination of digital surrogates.

Boundary

Clearly within: high‑resolution, color‑calibrated capture of a manuscript with preservation‑grade files and metadata. Boundary case: a smartphone photograph used for quick reference but not for preservation. Clearly outside: born‑digital artworks whose creation is inherently digital are not 'digitization' of a physical object.

Semantic Tension

Access/Openness ↔ Authenticity/Completeness/Stewardship — broad access goals can conflict with fidelity requirements, rights management, and the resources needed for long‑term digital preservation.

Synthesis

Digitization is a curatorial and technical decision that trades fidelity, cost and access; its value depends on deliberate capture standards and sustainable digital stewardship, and it complements but does not replace physical conservation.
