Superb advice from Chris.

I?d add that depending on the type of art
You may wish to consider a polarizing filter.
If the art uses a heavy impasto of glossy oil paint
The reflections may distract from the feeling of the painting.
Especially if she wishes to print ?facsimile? prints of the art.

If watercolor art - the texture of the paper can become a distraction
if attempting facsimile printing.
And require a hyper flat lighting approach to hold the ?texture? at a 
minimum.
