Just saw your post on Ganoskin and am having a heck of a time taking non reflective digital pictures with my 2 megapixel Fuji camera. I bought a Cloud Dome and thought that was the answer to my reflection problem but it wasn't, it fixed about 75%.
There are three things you can try…
A polarizing filter which reduces the glare by “bending” the
light – these are available to fit most cameras – but not all
A matte spray – available at camera supply stores – mine is
"Sureguard # 981" made by McDonald Pro-tectecta-Cote. I have also
used things like hairspray and fixative sprays (Art supply) in a
pinch. The disadvantage is that you have to clean the stuff of
A secondary diffuser between your light bulb/fixture and the
"dome" or cone itself.
Lastly, if you are really desperate and the surface allows it - I
have used ordinary oil based modeling clay/Plastelina formed into a
cylinder and “rolled” over the surface to dull it down. This is
kinda hard to do evenly, but it wipes right off with a paper towel
and you just try again…
