Hi Sheba,
Thanks for the reply. Unfortunately, yes, we've tried most of those things
(though not the digital camera). Spraying the brass black and putting it
against white paper does help, but there's still some reflection around the
edges that's tough to deal with. We've also tried Streamline with slight
success in some cases.
We've stuck with flatbed scanners over digital cameras because I've never
seen how a digital camera could give me a more accurate size? We've tried
about 6 different flatbeds, the last being an Epson Expression 1680 Pro.
Thanks very much for the thoughts... keep them coming! :)
Evan

A home remedy for shininess:
#1 Spray-paint brass black
#2 Place on white paper
#3 Photograph with digital camera
#4 Streamline
#5 Not accurate enough? Get a more expensive digital camera.
Just a thought. And you probably had it already. Oh well.
