| *One line summary* | Checking that an image collection digitised over 18 months by 4 separate suppliers consistently conform to specification |
| *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 |

| *Possible approaches* | * Run JHOVE/FITS on all images and check specific technical fields against specification.
* Run Java image library to extract image properties and compare. |
