Hi Algy... I am afraid I do not see much hope for that. I see that you shot it with your Galaxy and that was a good idea. Scanning something that is already a dot pattern, will often produce even less desirable results. It often results in a distractive moiré pattern. So a camera capture was a good idea. If you believe you have captured all that there is in the original, then it is likely that the halftone dot - first reproduced in newspapers in 1869 - is not very good in this reproduction. Also... if the original size isn't very large, then you are dealing with even less possible detail to begin with. Many of the early attempts by smaller papers did not hold fine detail. Highlights were blown out and blacks filled in quickly. Some publishers overexposed their screens in an effort to keep the 3/4 tone and shadows from filling in and subsequently blew out their highlights. Bottom line, it is hard enough to "descreen" modern newspaper halftone reproductions, and even more difficult with vintage impressions.
