I have a Canon 8600 flatbed scanner that works well, a friend had a bunch of 8X10 glass plates that scanned suprisingly well for the condition they are in. Two "buts"... if an area of photo is blown out it is too black for my scanner to process, also an area of deep shadow is too white to get any detail. If the exposure is "OK" I get a good negitive file that I can work with.
The over/under exposed plates are something I have been working on to try to light them from below and take a picture of the plate, several actually, and stack them in PS. So far, no workable process. Also, I'm only playing around with about 50 total, several hundred sounds overwhelming. I would be intrested to know how it works out for you and if you find a service that does it.Good luck.
