filmscanners: Color Cast removal/and blue blues

[mahimahi]

--Hello

I am having problems in regard to color cast removal when using the Nikon
LS1000/silverfast combination. The problem shots are underwater images which
include a deep blue background but end up pea green. Shots that do not
include a blue background.

I also use a Acer 2720s which the factory software includes a film type
selector. This helps a little but when scanning Fuji NPC 160 (which is not
included in the list of film types) produces similar green output.

Problem #2. (Positive film On both scanners) When trying to scan images with
a light blue background and a subject (Sperm Whale Infant) which is quite
different in tone from the background on the original. The resulting output
is all blue (whale and background). Any tweaking of the color in the scanner
software to bring out the color of the subject results a water background
that has a reddish purple tint.
