Karen - you seem to be referring to "cross polarization" a technique that
gobbles up many stops of light. But since one is working at close range with
flash that should be no problem.
George Lepp goes to great length at describing this technique in the first of
his excellent books "Beyond the basics." Peter should check this source out.
My only concern, however, is that the technique does such a good job at removing
spacular highlights that it may rob these works of art of the way they reflect
light and make photographs of them look flat compared to the vibrancy that
appears to the naked eye.
