Old Photograph Restoration Example

Here is 2 i done earlier last year...
Over the years these pictures have been used as paste boards, cutting boards etc, they were given to me to see if i could do anything to get them back to normal, each one took approx 6 hrs each, the original prints were about 18' x 14" and were taken in about 1915-16. comments are welcome but i will add that my mother-in-law was over the moon when she saw them. ( they are her mum & dad )

These were done early last year and restored in Photoshop CS, i cannot remember the precise tools used but if anyone needs to ask any question on how it was done i will try my very best to advise, but i can say it involved loads of cloning and dust / scratch removal,both photos were brighten up before any thing was done.
On the gentleman the right eye is a clone from the left due to a large smudge which showed up after i brighten the photo, a small catch-light was added to the right eye, samples of cloned hair was taken from different parts of undamaged hair to replace the damaged piece.
The Lady was much more difficult as there was damage to her face and nose, samples of skin tone (cloned) were taken very very close to the damaged area to keep it more natural, i must add it is easier said than done, both photos were then put through levels, brightness and contrast adjustments to suit your own personal view.
