hi kerry,
i started with selections in the background and used
psp's new color changer tool on these to darken a bit and put some color back.
i also selected out the people and used a lot of tiny clone at a medium and low opacity. there was also some push in there in very small areas or to clean up edges. i also ran
psp's digital camera noise removal on that selection.
and despite your warning about sharpening, i also ran a mild usb on the same selection as the digi noise removal...just a small amount
that was pretty much it. you could run some color balance or brightening also, but i wanted to keep it pretty much how it was when taken.
