For some reason this list isn't getting delivered to my mailbox yet, so pulled the above response off the recent archive.

There have been two different directions that museum partnerships with WMF groups have taken: quantity and quality.
The optimal solution is to seek a combination of the two.  A selection of highlights from the museum's collection that are

potentially feature-worthy certainly helps.  Neither the curators nor the average WMF volunteer, though, is familiar with the
parameters of feature-quality digital restoration.

The baseline is to get a good quality scan of at least 10 MB in uncompressed TIFF format. I don't call a file large if it's under

100 MB.  The largest image in my system right now is a 992.4 MB digitization of a historic Indonesian tapestry, courtesy of
the Tropenmuseum.

My long term goal is to partner with art schools and incorporate historic digital restorations into the curricula, and to scale up

our restoration output that way.

Something to keep in mind while you talk with them.  Would be delighted if you keep me in the loop about how the London
museum community is responding, David.

Cheers,
