My mother has a lot of Kodacolor II negatives from the late '70s to the early '80s. I've scanned many of them with my CanoScan FS4000 and the results have been very disappointing. The negs appear to be faded, which results in a very dark image when scanned. Additionally, the areas of the image that should be dark (shadow areas) tend to be greenish. I'll post an example so you can see what I'm talking about. This was actually the best of the bunch. Most of them came out much darker and the colors were much more messed up. Basically, is there anything I can do in Photoshop to fix these? I've tried playing with brightness, contrast, and color balance... are there are things I should be doing?
