I have a photo and I scanned it, but the scanned version introduced a lot of white spots on the image. I think the problem is the type of paper of the photo, which is not smooth a bit rough. There's something I can do? some technique to scan it? or post processing it? I tried a denoiser filter which didn't make any difference.
This is just part of the original image scanned at 2400dpi
