Only one thing occurs to me, Chuck. The reflected light from the glass was,
by virtue of being reflected, also polarized. Could the sensors of the A1
and 20D react differently to polarized light? I am talking here of the
"digital film" rather than the exposure meters (as I understand it, you
didn't use the camera meters).

No OM content at all. Just a perplexing exposure problem that I'd like to
present to the combined wisdom of the list.
Yesterday I was assisting a friend in shooting a collection of water
color paintings for a local artist. The paintings were framed and
under glass.
