I'm not sure how a "spectroradiometer" works.  Is is like a very 
accurate spot meter that can read at a distance?

I think the problem might be that the amount of reflections is too 
dependent on the particular environment, for example, how much light is 
behind the viewer.

Very roughly, I've used as my "minimum acceptable" dmax figures 1.6 for 
matte and 2.0 for glossy.
