Well, I got to thinking... MAYBE I could do at least a LITTLE with them in Paint Shop Pro! Sooo... here is my lame results after a couple hours of work...
Granted, I think they came out better than I expected. I improved on the original snaps by scanning at the highest resolution Paint Shop Pro would let me, 600dpi, which resulted in a LARGE, over 10MB image. I then cropped the area with the performers. After that I resized to a smaller size for posting on the internet. Finally, I sharpened the image as much as possible, and used the JPEG artifact removal feature.
I was surprised you could actually see their faces now, although a bit blurry still. Wish I had thought about doing this sooner!
I still remember there were signs up in the arena saying "No Cameras Allowed". Since it was a pocket sized camera, I'd whip it out from time to time and take a snap. A university "union board" person walked up to me at one point, said "You KNOW you aren't supposed to be taking pictures, don't you?" I said, "Uhh...yeah." He then smiled, said, "Don't worry, I didn't see anything.", and walked off. I took a few more pictures after that, being the rebel I am! :-)
