Mkay, well, first off I changed the color balance, made it a little warmer so her lips weren't as cold. I than went over her face with the spot healing tool (the one with the band-aid) and went over anything that wasn't smooth. After that, I dodged the iris and corneas and the teeth to make them a little brighter. After that, I added a bit of a diffuse glow to make the drss a bit whiter and than flattened the image. I duplicated the layer and added a gaussien blur, set the opacity to 45%. I went back down to the background layer and sharpened it to retain detail. I sharpened the eyes a bit more. done.
Pretty much, it smooths everything out while still keeping it sharp.
1) Make a duplicate layer;
2) Open the Gaussian blur filter and change the radius until the grunge just becomes invisible. Be careful here, getting the radius right is very important. Note the radius and cancel the filter;
3) Apply the High-pass filter at the radius you just noted down;
4) Apply the Gaussian blur on this layer at 1/3 of the radius;
5) Invert the layer (<Ctrl><I>), set the blending to Linear Light and the opacity to 50%;
6) Apply a Hide-all mask and paint white where you want to degrunge.
then I merged all to another layer
made a saturation adjustment layer and removed some red from face (masked outchest/shoulders - they are pale enough)
There's definitely room to 'save' these picts. My feeble PS skills got a pretty decent result. For the sockets I just duped a layer, burned and then played with opacity until it looked right. I slight 'glow' effect softens it up and improves it a bit more.
Here is my edit... just quickly in photoshop. (before and after)
dup layer > screen > mask the face
dup layer >levels and curves > mask in the eyes
dup layer > healing brush to remove blemishes/flaws/under eye bags
Dodged eyes and teeth
removed redness and prominence from the tip of the nose.
dup layer > air brush filter (opacity set to 35%) > mask in only skin
dup layer > Sharpen
