Here is an example of faded Kodak Eastman print stock, typical for the 1960’s and 70’s. Yes, it is really that red.
Usually I grab every 100th frame and look for some outdoor shot with natural lighting to start colour correcting. Most of the time, but not always there will be some colour buried in the reds.
Once the colour correction is set up using some sample frames, every 100th frame is processed again to get a general idea of the result.
Normally I would saturate the corrected images a bit more. do not do this at the time I generate the frame by frame jpegs, but rather when they are composed into a moving sequence. I take this approach because it is hard to judge the effect of a saturation boost without viewing the entire film
When colour-correcting this old Eastman stock the result can vary from poor to full rich colours. In this gallery I would describe the results as pretty good, but more saturation will be added.
One of the problems with the fading of the Eastman print stock, aside from the colour shifting is that highlights get bleached right out and there is not much you can do about that.
This film had an added challenge in that a lot of interior lighting was used making adjusting the colour a bit trickier.
