I found a case of old 35 mm slides from over 40 years ago most of which were in good condition.

I scanned them onto my computer as jpg files and had a look at them, most were good quality for their age but a few taken indoors were a bit flat and colourless, I added the folder to Mezzmo and they all streamed to my TV without a problem.

I loaded the poor ones into PaintShop x8 and messed about with them, I eventually used Edit, Adjust, Colour, Fade Correction to get a half descent picture which I saved. They all looked OK on the computer but when I looked at the 'altered' ones in Mezzno they hadn't changed and looked like the pre-adjusted ones, I tried transcoding them which didn't help, when I tried to steam them all I got was a white screen, the untouched ones streamed fine.

I suspect it's something to do with the interpretation of the jpg file by PhotoShop but I'm a bit of a novice in that direction, a bit of advice would be helpful.

Thanks in advance.
