I have many cheap-minilab processed color negatives from the 1980s and 90s that are so faded and color shifted it took a lot of work to correct them after scanning. Stuff from the pre minilab days is all great.

Anything I ever had done by Kodak labs is still absolutely beautiful - especially the prints.

I want to keep both the original film and the scans for double insurance. It is unlikely I will ever optically print color snapshots but there could be better scanning options in the future.

I have read of people that scan all their old negatives and slides and then throw the originals all away, believing they will never need them again.
