Remove photo sheet repeating pattern from restoring Black and White old photo
Hello everyone, hope someone can give me some directions on how to restore some Black and White old photo.
The problem that I encountered is that those old photos were printed on matt paper. After scanning them into the PC, I have trouble to remove those paper style pattern. I searched whether Adobe Photoshop has a function to remove situtaion like that, but I have no luck. The closest one I can find is RetouchPro. However, I want to avoid using 3rd party program as much as possible.
Does anyone have expertise on this field? Thank you very much!!
Picture i have to edit (The face part must be cleaned because the dotted pattern is too obvious) (I have over 100 photo with similar situation)

Solution found at yotube, but want to avoid as it is a third party software

Thank you everyone for reading this post!
