I bought a couple of boxes of old (end 1920's) negatives and glass plates in a brocante shop a few years ago while traveling in France. As I was now scanning I tought to give those a go. I know from a quick inspection when I bought them that they were in not so good condition, both from storage (in the cardboard boxes) and from handling in the shop. But how should I proceed to get the best out of them? They seem to be well eaten by fungus. I took a few shots of the one on top:



Both sides in glancing light, you see the spots very well.




I do have some Fotospeed FC50 film cleaner at hand. Would this be a good idea? Or put them in the Jobo tank with some water and photoflow?
