Susie, I would say you did a very good job. I wish I could take credit for the duplicate and move layer method. Actually I learned it from Katrin Eismann's book, Photoshop Restoration and Retouching.
Janice, The FFT filter takes some practice to learn to use, and not all FFT filters are the same. Some of the free ones don't work very well. Even with a good filter, it only works with a very regular pattern that can be defined mathematically, which is how it works. I won't pretend to understand the math, (Because I don't have a clue). One thing that I have found in using it though is when looking at the tutorials that I have found, they say that you should put a gray spot over the star that it creates. I found what works better is to paint a gray pattern in the shape of the star, usually shaped like a plus sign. I paint it with the color of gray in the bulk of the pattern with a soft brush set to slightly smaller than the center of the star. This method seems to work a lot better for me. The FFT filter that I am using I got from www.4n6site.com
. The people there will let you have it for free, but you need to send them an email and ask for it.
