... If you have the time could you post what sort of wayback machine you are digitizing these with?
Thank you. It's been a lot of work, but great fun too scanning my slides and negatives. I chose the Epson V800 for my scanner because of its versatility, quality and capacity. I have thousands of slides and negatives and I'll soon be scanning my parent's many slides.
I chose the Epson V800 in late 2019, but Epson quit offering the V800 this year. It's opened a terribly wide price gap between their remaining models -- the V600 ($230) and the V850 ($1,150). The V600 is an excellent scanner. The only reason I didn't choose it was because it scans 4 Slides/Scan, while the V800 (and V850) work 12 Slides/Scan. The V800/V850 also contain internal lenses for sharper results.
I'm generally pleased with the results, but scans of darker slides look terrible and there's nothing that can be done to improve them. Some sharp slides scan blurry on my V800 and there's nothing that can be done to help. I rarely use the Digital ICE feature because it's incompatible with Kodachrome, Plus-X or Tri-X, which most of my images were shot on.
I know a guy who does book publishing and he said that scanning slides is sometimes a strange thing. He has slides that scan great on one brand of scanner, yet look awful when scanned on another brand and other slides that yield the opposite!
