Do they always take the image from straight on, front? Is the camera panned around with a narrow FOV so that it doesn't see portions of the canvas from an angle? Does the light source move with the camera?

Or, I'm thinking, it's often really interesting to see the 3D texture of a painting -- is that ever something desired to be recorded? For example, with impressionist / pointillist paintings I've seen in person, looking at the canvas from a very low angle is even more interesting to be able to see the brush strokes than seeing it directly face-on.

I took a geology class in college where we studied a lot of high res photos of both individual rocks and larger rock formations. They used some sort of moving bed and a microscope for the rocks so you could get really close up while also seeing larger features. The formations we're photographed using a GigaPan mount that would allow you to attach a camera with a telephoto lens and it would step in both X and Y axis to create hundreds of images it would later stitch into a composite.
