I have boxes of old family photos to scan and clean up. One of the biggest problems is removing the paper texture. Fourier analysis works for regular patterns but often the texture is from sticky album sheets, matte portrait paper, etc… Face recovery seems to do a great job on the face, but the pattern remains starting at the neck and persists across the rest of the image. Is it possible to extend the pattern removal to the rest of the image?
Try actually turning down the Face Recovery strength and turning up the Upscale strength. This will enhance the resolution across the image.
