Carlos,
I have 'played' about with outdated Kodacolor II negative film and
Ektachrome 100 Pro - both recently exposed and processed with unknown
storage history - which have a blue cast but other colours have become
distorted too.
I have used Digital ROC on my Minolta Dimage Multiscan Pro scanner (colour
improvement) which with works with faded colours but not with a strong
colour cast like these images. I also use ICE for dust removal.
People critisise the Minolta software and recommend Viewscan or Silverfast
but I have never really got on with Viewscan - I do not find it to have
subtle enough control. Silverfast do not have a driver for my scanner.
I have found that I can quickly improve the colours in Photoshop by
adjusting overall Brightness & Contrast, Colour Balance, individual RGB
Curves, then Hue & Saturation and Levels and then if required, a bit more
Brightness & Contrast.
It does not take that long, and after a while it is easier to judge which
way to go.
There is also the fact that we are now used to bright saturated colours and
old film did not have that vibrance so it will be very difficult to bring
those colours up to 21st century expectations.
Kodachrome is different and should last well. I have some from the 60's
taken on my Instamatic 100 and the colours are still very realistic. I
always thought that Kodachrome was expected to last almost forever.
