As I thought I had said, we discourage them from photographing ORIGINAL works of art. As far as I am concerned, they can shoot away at repros till the cows come home, provided they don't bother other people. I find that most of the people who photograph museums these days come with video, rather than still cameras, and the low-light capabilities of modern video cameras eliminates the strain on both the artifacts and the people, unless you get clipped on the head by some idiot panning without watching what he/she is doing!
