| Detailed description |
Over time:
- check that each supplier has produced images which conform to the specification
- check that post-processing has been applied consistently (potential further problem - inconsistency in the source material - non-uniform photographs differ significantly from each other)
- check that metadata fields in the image are populated - identifiers, correct correlation to physical properties
Between suppliers:
- check that each supplier has conformed to the specification (resolution, bit-depth, colour-space, etc.)
- check that post-processing has been performed consistently - use of same processes, same bounds for applying e.g. level balance
- check that metadata fields in the image are populated - identifiers, correct correlation to physical properties
