For me, it totally depends on the end use for the photo. Some photos I simply want as a record of a moment in time. Those photos just get basics in the processing - mainly sharpening. If the photo is for an entry in a Creative competition, then I'll go for it! It's much more fun photoshopping than taking photos

I do get upset when repairing old photos, if someone asks me to remove a bush, house, or alter a person's appearance. These old photos are a record of our history, and it seems like desecrating our past to manipulate them. You have to feel sorry for our future generations. They'll never know if a particular photo is a true record or not.
