That's gonna be a fair bit'o work to really fix that up Namvet... just so ya know.
I've taken the liberty of creating a PSD file showing a method of getting the results you asked about.
Here's an outline:
1) lightened hair using Curves Adjustment Layer on hair selection.
(
i saved the settings for you)
2) Ligthened the eyes using white paint (
new layer) and Overlay blend mode;
plus Opacity reduction.
3) Sharpened overall photo using High-Pass filter (3.5) on a duplicate of photo, then set to Overlay blend mode, and reduced the Opacity a little.
4) Removed moire/mottled effect (
see inset) using Median filter on a duplicate selection of facial (
skin) area.
(
my newest tutorial on the site covers this subject in detail)
5) Used Channel Mixer Adjustment Layer to change photo to B&W. You should go to B&W first i think, before going back to Sepia Tone; if you choose to. It's just easier to repair in B&W first.
You'll need to tweak the curves settings a bit to suit your specific needs, but the settings i saved can at least give you a jump start with it.
The PSD file is too larger to attach here Namvet, PM me your email addy and i'll email the file to ya.
