I Would I have better luck if I took it to a professional photographer?
Let's put it this way. You can do the job yourself and if you spend enough time with it you can do quite a credible job. But if you take it to a professional, that person has all the tools, is familiar with using them, and can turn the project around quite quickly.
Hi, happened to see your post and LOVE to edit and restore
photos...just opened FamilyTies at www.pics-ties.com....
I'd be glad to look at the photo (free) or help you. There
is a before and after of a restoration on my web site.
