![]() ![]() use crossed polarizers - one on the lights in one direction, one on the lens in the opposite direction.You can play with the positions of the two lights to eliminate the texture. 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. Assign second scan 50% opacity to blend images together.Auto-Align Layers using Photoshop command.Import it as a layer on top of the first scan.In Photoshop, un-rotate the second scan.Rotate the photo 180% on the scanner and scan again.If you know some scripting or programming you could impose this elimination pattern automatically on an entire set. ![]() If you have the original image window selected, you'll get an error saying "Frequency domain image required".)Īnd if you can do this at higher resolution than you need, you can downsize the image with lanczos resampling for an even better result: ![]() (Note: You need to have the FFT image window selected when you try to do the inverse FFT. If you overdo it, you will get banding around the edges and borders. Make the black points big enough but not too big (play around with it). Use the paintbrush to eliminate the other stars. Now, don't remove the center point as that is the "DC" value. This is the pattern to recognize when you open the image again, and do FFT on the whole thing: Then select the part that's only white with texture. 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).

You can see a demonstration of the features in the attached video. If necessary, you can add a gradient map, and then the possibilities for editing the color become countless. Working with color takes place in curves that are already set to a more or less universal analog preset. Each of the projects will output a file with a texture of different sizes of the photocopy. The set contains 3 files that are identical in content, but different in size.
