Sarj Bloom provided this Taipei street scene from the early 1960s. He mentioned that he had to do a lot of retouching because the original slide had deteriorated so badly over the past 40 years. I've run into the same issue with many of my own slides and photos from the 50s and 60s.
If it's been a few years since you've dug back through those old photo albums or boxes of slides, I'd strongly recommend that you do it soon. Those precious images of places, friends and family may be lost forever if you don't take corrective action, such as digitizing them and using photo editing software to touch them up.
With my own family photos, I scanned them, touched them up, and then made copies for other family members. None of this is terribly expensive, though it does require a time commitment. But the satisfaction in knowing that you've preserved some important historical images is hard to put a price on.
Nice job on this one, Sarj!
