Re: Glass Negatives
I've scanned glass plate negatives very successfully with an Epson V750 Pro. If you're using a different scanner, it needs to allow the light to shine through the negative (as for slides). The 750 has a setting for document type called "film (with film area guide)" -- this allows the scanner to scan film that is not a standard size. For film type, choose "black and white negative film". Put the glass plate negative on the scanner glass, emulsion side down. (Be careful, so you don't scratch the glass plate or the scanner glass.) Then pick the settings according to your project. I always scan in color at 24 bits and usually at 1200 dpi -- I've tried 48 bit but don't see much difference in detail captured at the higher bit depth. If the image has detail I'm trying to get a good look at (words on signs, details of buildings, etc) I might scan at 1800 or 2400 but, of course, be prepared for a really large file size at these numbers. Images from glass plates are a real treasure trove -- the amount of detail preserved in these old negatives is amazing -- in my opinion, they're the closest thing we can get to a "wayback" machine. Good luck with your project.
