Ok, I went to scan some of my negatives from a trip to California back in 2001, but much to my dismay I am finding what looks like little pieces of the emulsion have been scratched off the negative. I scanned them with my Dual Scan IV, and at first it looks like bad dust flakes, but if I take a closer look it almost looks like it flaked off in that spot. I tried cleaning with PEC, but no change! They have been stored in an 'Archival' sleeve. Print file brand non PVC, supposed to be good for archival storage, but what gives here. I know back then I didn't know how bad QC at the 1-hour mini labs could be, and that could be the case here, but I am not sure. Is there a better may to store negatives??
