Do you know how to clean old negatives for scanning?
In my dumb city, I went to a photo service, that do something similar to Kodak photo CD, to try scan 35mm negatives to restore digital myself, and they said they only work in JPG. I tried to explain about bit depth, importante specially to restore faded 35mm film negative image. I said everything need, gave example that if a layer is 80% faded, a JGP that have only 256 tonalities per channels and would get just just 1/5 of it (51 tonalities) after enhance the blue channel to recover the color.
I explained that they just needed to gime the fotos scanned in at least 10 bit per channel, that all good scanner could do, and they only needed to adjust to save the image in a good format. But the dumbness was all around there, and they only keep saying: We only work in JPG.
I could hang someone there this day...
If these silly guys don't even give a damn to bit depth quality to recover color, what would I expect about cleaning the negatives prior scanning. I would not even risk to let they do it.
Some sites talk about isopropyl alcohol, but other said it would destroy film emulsion.
It would be interesting to compare the sound of the original (probably restored) with the sound of a new (recreation folowing Cristofori design):
