B&W Photo Restoration

[Dwig]

The only diference between that photo and the orginial, is the background.

Then the problem with the print is not grain. It has some form of deterioration and the only recourse is retouching using the techniques mentioned in several of the other replys.

Still, it does look very much like the interence pattern that results from having the scan resolution too near the spatial frequency of the grain. That can easily occur and when it does, the cure is to rescan at either a much higher resolution or at a lower resolution.
