One line summary	Checking whether a photographic print and negative collection are mutually complete
Detailed description	A photographic collection contains negatives and prints. The prints are, in most cases, prints from the negatives, but we don't know if we have all the negatives of which we have prints or if we have prints for all the negatives.
Issue champion	n/a - shelved
Possible approaches	Use Perceptual Image Diff to identify when an image is a version of another (e.g. a print made from a negative) Possible problems - finding the right tolerance calibration as images will not be identical but surrogates produced via an imperfect, variable, physical process
Context	This is probably a cataloguing problem rather than a preservation problem!
