[Leica] IMGS: Color Balancing (Blue Trees)

[Tina Manley]

PESO:

I'm scanning 7000 slides from Switzerland, most of them Kodachromes, most
from 1989.  One category is 56773 - Switzerland Countryside.  If you have
been to Switzerland, you know that the Swiss countryside is beautiful.  I
want to get it right.  Here is the original scan, scanned on the Nikon
LS5000 with Vuescan set for Kodachrome:

It's too dark and the trees are blue.

I lightened it and balanced the color based on the white house in the
foreground:

Everything looks fine except the trees in the distance are blue.  I
remember them being blue but maybe I'm wrong.  I subtracted the blue.

Now everything looks too green.  I have many, many of these slides to
adjust and want to get it right but believable.

What do you think?

C&C greatly appreciated.
