@Redflag Thanks. I thought, since I wasn't trying to win a prize, I'd go a little experimental and push those RGB dials and see what damage I could do. Of course, now that it's done, and posted, I can think of a million things I could've done better. I wish, now, I'd stuck in a billboard and captured the reflection of the photographer on the side of the car, but this is what you get when you wait 'til the last moment to not enter a competition.
You probably already own all the software you need to restore your old polaroids, but I'll bet there's an AI program out there that'll do the whole thing for you with a single click.
