Problem:
Need to remove texture from a scanned older photo in Photoshop
I recently ran into a problem while attempting to scan an older photo into Photoshop. The print was textured with lots of little divots, so that when I scanned it into Photoshop, it ended up having lots of little reflections from the scanner light.

Before
This is an older photo, probably printed in the 70’s, and the texture on the print is just out of control.

Solution:
I found that the best way to remove the texture in Photoshop was to:

1. scan the image in at about 3 times the needed resolution, so if you need to print the image at 3×5 at 200dpi, scan it in at 3×5 at 600dpi.

2. Then run the dust and scratches filter, under Noise in the filter menu. I used Radius: 7, Threshold: 0 for my settings, but you may need more or less on the Threshold setting.

3. Reduce the size of the image back down to the resolution you need. Image > Image Size

4. If needed, use a bit of a sharpen filter, but I didn’t really find that necessary.

After
After the dust and scratches Photoshop filter is applied, and the size is reduced, the texture is gone.
