When scanning a photo printed on textured paper, the texture will show up in the scanned image which is very difficult to remove, as seen in the following image:
If the texture is a fixed pattern type like the above picture, then there is a useful technique I recently discovered that can reduce the appearance of the texture. This technique does not ivolve using noise reduction software such as Neat Image or using blurring, and there is actually some gain in details as compared with using noise reduction software.
Here's the repaired photo using this technique, with additional processing with the healing brush to repair the scratches:
What do you think of the result of this technique? And can you guess how it was done?
