Some more blogs on this raised some interesting points. First I'll
quote what I said earlier, and then comment after it.

Now look at this blog and the comments on it:

The comments that do a much better of job of explaining what I was
trying to say above are here:

Some quotes to give a taste of the arguments being put forward:

"A large format camera with a betterlight scanback is rigidly attached
to a display platform where the art is placed, along with the
lighting. All the camera movements, focus, etc, are fixed except a
rail allows the camera to be adjusted to match the measured depth of
the frame. Images of a calibration target are taken, then the art.
Basically scanner turned inside out and scaled up to a large size."

"there's actually quite a lot of skill required in using the system.
Each image require individual calibration, and an appropriate lighting
direction needs to be chosen. You wouldn't light a Turner in the same
way as a Van Gogh. So the NPG can argue that skill has been required."

"[C]opying technology has reached a stage now where exact replicas of
works of art can be created. The resulting digital files that drive
the 3D printers, or CNC machines to reproduce the work may be the
culmination of months of work and the expenditure of £10000s."

"The HP system involves custom calibration and lighting to produce a
version of the image that gives a remarkably accurate 3D image of the
paint surface and texture; it takes a lot of time (a decade for the
permanent collection at the NG I think), costs a lot of money, needs
training of the operators and is used as the basis of the print on
demand system in the National Gallery shop."

"Suppose the Van Gogh museum did produce high quality copies of their
collection, such copies would be a colossal public benefit, as would
the cost of creating the digitization. Now say those files leak out,
should the museum have any ability to stop someone from using those
files to produce and sell exact copies, and if they don't, if someone
can just snag their production data, what incentive do they have in
make the artifacts available in the first place? And so we return to
the NPG. Just how do they protect their investment in producing their
digital files?"

These issues of how to fund digitisation projects and what protection
should be afforded, if any, are not going to go away.
