Does anyone know how I might be able to eliminate this pattern from
the image using Photoshop?
Thanks in advance!

The problem is called 'moire pattern'. If your scanner has a
'descreening' option, turn it on. There are other approaches, but this
seems to be the simplest to use.


Not a moire but a texured paper, descreening on a coarse setting will
get rid of the pattern but at the price of less sharpness. This will
be better than any photoshop function. I second the previous post
saying I hate this paper.

It was very popular when I did weddings eons ago. The proofs were delivered
to the couple on "E" type paper to prevent this very thing (with cameras).

In some cases, the paper is DESIGNED to prevent copying, but some
improvement can be made with descreening. I also hate these papers, but
they do have a right to prevent copying.

At some level they have the right, yes.

And if the studio is dead and gone, or the old negatives discarded, and
they *can't* sell you additional prints, then you have the right to
curse their name, too.

And remember this next time you pick where to get portraits taken.

I have never paid to have portraits taken, as best I can recall. Not
that narcissistic. Grin.
I did take a girlfriend to a pro for photos once, but his camera never
worked again after that. Dumped the girlfriend too. Grin.
