The outcome
Deliver a restoration derivative that is useful and transparent without replacing the authoritative source.
Step by step
A workflow you can repeat.
- 01
Create a lossless master scan, checksum it, preserve metadata, and document provenance, physical condition, known subjects, intended use, and authenticity limits.
- 02
Choose local processing for sensitive material, duplicate the master, and test denoise, sharpen, face recovery, and upscale on representative crops at conservative settings.
- 03
Compare each result with the source at native and target size, watching for invented facial features, text, fabric, edges, grain loss, halos, and false detail.
- 04
Select the minimum effective model strength, make reversible conventional edits separately, and keep model names, versions, settings, and intermediate exports.
- 05
Label the result as restored, retain the untouched master as authoritative, obtain rights and archive approval, and deliver both source and derivative with documentation.
Working standard
What good use looks like.
- Never overwrite the archival master.
- Use the minimum effective strength.
- Label restored derivatives clearly.
