I acquired some 35mm color slides from the 1960s. A few years ago I had an imaging shop convert a few of them to tiffs which were around 20mb files. The quality was crap considering the large file size, and it blew me away to see how bad they were (they look grainy and thin). I've edited some, and a few didn't look too bad afterward. I can edit scanned images (and still will), but I would like a better starting point than before. What should I be looking for in the way of processing slides to digital files when it comes to looking for someone else to do it? Or is there not a way to get quality scanned images from old slides like these? Thanks for listening.
