thanks for reply. I'm using vuescan for years, I scanned a roll of commercial developed film yesterday, with good result. Anyway, thanks for your idea, and I will try to edit tiff file and see if I can correct the color fading problem.
here's the commercial developed film , and I scan it with epson V600.
Color negative film can register much higher contrast than a JPG file or photographic paper. When you scan negative film, and especially with motives that have a high scene brightness ratio, the scanner post processing software will compress contrast to make it fit into 8 bit color space. As a result, the image will look faded and contrastless, just as if you print a b&w neg on gradation 0 paper. Get the negs printed optically and you'll see that colors are most likely fine and dandy. If you insist on hybrid work flow, plan for digital post processing on your computer.
PS: I realize that this topic reaches deeply into DPUG area. Reason I think it should still be discussed here on APUG is because many people judge color negatives based on poor and unprocessed scans and reach very wrong conclusions about the film material and its development.
Trying to be the best of whatever I am, even if what I am is no good.
In our local area , only one shop can process c41 , but then films that processed by them looks dirty and scratches sometime. otherwise films that developed by them can be really easy to scan with correct color reproduction.
I purchased Unicolor c41 kit recently, just because I want to get rid of scratches and dirty film from local shop.
No manual enlarge service in our country now, they will just scan it either Noritsu or Fuji Frontier scanner and print it .
I used Acer scanwit 2740 for years, ( with vuescan software ) and bought Epson V600 recently, for medium format scan.
