It is a Commons sort of thing. And we should have not only tutorials
about museum photography but also on other areas. Teaching our users how
to take pictures to be published in Commons our responsibility.

I think that it is at least relevant for Commons to have and produce such documentation, and it is probably the sort of form that Wikiversity takes. Maybe we could consider setting up an informatl special interest group or "task force" to create such things on Wikiversity.

  Rama: I miss some examples of good museum pictures on the tutorial,
you included mostly what not to do.

Because I suck, so I have lots of examples of the  later and few of the former :p
Actually, I only put my own images as examples of things to do if they have been promoted to QI or FP beforehand; and it is difficult to give examples of images made by other people because I don't know the specific difficulties that they encountered to make them. I would be very grateful if someone could exhibit examples of good images which were produced by compromising on some particular aspect.
