Hi Julie, We scan negatives at the highest resolution the scanner can do and store the files as TIFFs. Depending on the scanner, sometimes the files can be quite large (30-50 mgs for BW)and we store them on external hard drives. We also re-format them to to sizes 8 x 10 @ 350 dpi TIFF (for print quality that covers most publication needs) and 5 x 7 @ 150 jpeg (for powerpoints, reference databases, etc) and keep them separately for easier access. We feel it is best to scan once to cover all potential needs especially if the negatives are glass or nitrate based and should not be handled over and over again. Hope this helps.

They are about 3.5" square. We will be creating master TIFFs of course, but we would like to be able to print larger than 3.5" images. Is it better to scale up and scan them at something like 200%, or to increase the resolution from 600 dpi to a higher dpi?
