ok, this is just to get you going. yes, this can be helped. but, it's going to take some work.
to start, we want to find the image a bit and maybe do some cleanup in the process. here's how i progressed. this is NOT finished. this is just the easy part.
1. duplicate background
2. clarify at a setting of 2 on duplicate.
3. duplicate that.
4. usm at 10/100/5
5. duplicate that.
6. digital camera noise removal. i didnt do a full setting here. i just wanted to clean up part of it without overly blurring things. Neat Image would work here too.
7. duplicate that layer.
8. normally, i wouldnt do this next thing but because this is just an example i took a shortcut here. i resized the image downward so i could use the Polaroid dust and scratch remover within paint shop pro. anything over 800 pixels on a side and you have to use it in stand-alone mode. so, i just cheated a bit here.
8a. removed for black specs.
8b. duplicated that layer.
8c. removed for white specs. again, on both the black and white spec removal, i dont want to do a full filtering to effect too much blurring.
9. duplicate to new layer.
10. paint shop pro has a really nice feature for putting eyes back in an image. it's their red eye removal tool. i could have done this by hand, but in this image the eyes were pretty messed up so i just rebuilt them. also, i shld have resized the image back up to the original size here, but forgot and did it afterwards. it would have given me a slightly better look had i done so.
11. resized back to original size.
so, you may look at what i post here and go, well, that's not all that good. like i said, that was the easy part. the next part would be clone, airbrush, and push (smudge) to put back more of the detail and remove more of the damage and that could take hours.
so, that's one way to go to get started
