Beautiful job.
There's something really satisfying about doing this kind of work.
I once did a restoration, where upon working with a very high res scan of the original I discoverd two little babies in baptismal gowns (all white) sitting on the grandma's lap in the group photo! None of the family knew they were there in the original.
Preserving family history like this is a worthwhile endeavor, and digital processing is very well suited for the work.
Again, a lovely job!!!
