Hi anneymouse
Can I just ask if this is the original scan of this photo, because it looks to me like it has been put through some kind of filter.
If you can get hold of the photo and can rescan it, would it be possible to post that? If not, I'm afraid that the results may not be too good, because most of the detail, especially in the eyes, has been lost and would be extremely difficult to repair. It could be done, but the result would be far from satisfactory.
Hope you can post a clearer copy to work on
Regards
Glen
