The best thing you can do is to put it on a copy stand with two lights on goosenecks and re-shoot with a good digital camera. Hey, what does it cost to try, right? If it works for you, tell your friends.ĭo you still have access to the original photos? I also think this process may help reduce subsequent destructive filtering for random textures such as light scratches. I was able to further clear things up a tiny bit by copy-pasting the "Difference" between the two aligned scans into a new Difference level at about 10% opacity, but I've never been brilliant at those level filters at the bottom of the list.
But the big plus is that it DOESN'T remove any information from the photo, providing a much cleaner baseline which should require less-destructive settings in subsequent filtering. maybe 2 more scans at 90 and 270 degrees added to the mix would do more. Blending two such scans together cancels out most of the texture this way. This technique comes from observing that the highlights and shadows of the photo paper texture are largely reversed when scanned from the opposite direction.
The parts you need are:įirst, load your image. When you open the program it is a strip of menu.
I will explain how to find the correct filter, that you can basically do manually in ImageJ (freeware java app). The textbook method is, as others mentioned, to suppress the texture in frequency space.
