A recent acquisition of some old Academy images brought up some thorny problems. The photographs, taken by Edwin L. Cunningham in the early 1900s, were in very rough shape, with prints exhibiting extensive waterstaining, thick layers of surface grime, and in some cases, obvious mold growth, and glass plate negatives which were either broken or rendered entirely useless by having been stuck together for decades. While we accepted many of the images for scanning, once completed, they were returned to the donor as they were pretty much at the point where physically restoring them would have been either been prohibitively expensive, or in most cases, an act of futility.
Once we had good “master” scans of the images (meaning that no editing is done besides rotating and cropping), we set about making “user” copies, where we employed some fairly basic Photoshop techniques to make the images usable again for possible online publication and/or physical printing. Deciding exactly how much editing to do can be a tricky business, but we tended to be a bit conservative on this project. Basically, we simply tried to minimize the most visually damaged elements, rather than attempting to bring the images back to a pristine state.
