Don't waste your time, Drew. If someone wants to, they can Photoshop the JPEG image; otherwise the content is far more important than someone's idea of "technical excellence" (besides, it's still a lot better than a lot of the scanned images I've seen from the same period). As you said, there's not much chance of replicating that shot (483's going to need a complete rebuild - including a new boiler - before she'll ever run again, and the depot and surrounding area have changed enough that it's hard to tell just where it's at from street level unless you know where to look; heck, I lived in Aztec for six years and didn't know where the depot was until a year before I moved to Albuquerque!), so if someone doesn't like the color quality that person can fix it him/herself!
