preserving / ressurecting old docs?

Pardon me if I missed someone raising this issue yesterday, but if you're scanning grey level images, it might be worth seeing what happens if you raise the resolution and switch from grey level to black & white (line art) scans -- one bit per pixel. Then you can raise the resolution from 100x100 to 300x300 (9 times the pixels) , and end up with only a 12% increase in filesize. Photos & halftoned images don't suffer this well, but the text and line art will be much better off. This requires you to take some care setting the contrast and black level when preparing to scan, though. Alternately you could scan at 300x300 greyscale (8 bits per pixel ) and run the pages through a filter to reduce the bit depth automate that process, though. Before embarking on this huge project, it might be worth trying a few different techniques to obtain sharper images while keeping the file sizes reasonable. Brian
