Bill,

Besides the polarizer that the Duck and others have suggested, you want to at
least try not to create any of the reflections yourself. This may be a time
for the flat black shirt or windbreaker that all wedding photographers carry.
Also, you should try to keep the light source that powers the reflections to
your back, if possible.

This sounds like a museum situation, where the object may be confined to a
climate-controlled case that you're not likely to get opened. If so, you might
try asking one of the museum curators what they do when they want to
photograph that or similar objects. For example, maybe they could turn down
the room lights for you at the end of the day. They may or may not be
cooperative, but it can't hurt to try.


In some cases, if you have a lens hood and the right focal length and can focus close enough, merely hold the hood against the glass (gently, if your AF makes the tip of the lens rotate or extend). This eliminates all reflections on the glass, makes sure the lens axis is perpendicular to the right things (no perspective-induced distortion), and stabilizes the camera which allows for longer exposures.
