I have a few ancient family photos that were sent to me long ago by relatives now dead. What they sent me was some kind of plain paper scan/print of the original. They have a regular pattern of lighter/darker vertical lines across them, either from a poor scan or from a poor print or some combination. So this is my source material. They are b/w and unique. Some of my relatives have asked for copies, and i'm trying to figure out how / if I can improve the quality. Attached below is a detail enlargement of the image showing this banding. I'm not sure even what to call this. Its almost like some kind of vertical halftone print. Thanks for any ideas or suggestions.
