Hi Peter:

Here's your original:

Here's the one which I sent to you last night
http://www.hemenway.com/for_peter/not-so-blue.jpg

All I did was a little color balance, less blue and a little more red...
but it was late and I can't remember the amounts.

You replied... >>> It is indeed better, Jim.  In fact the fur colors are
more vivid than the actually were.  But there's still blue stuff
adjacent to the white fur, and in the places where the winter fur has
been shed.

I've read that the LS-2000 suffers from blue "bloom" when you have dark 
things next to light things.  There is a tiny hint of blue in the
original 
slide, but *nothing* like the way it comes out in a scan.

What did you do to get the fur nicer? <<<<<<<

Here's a 2nd try which I just did a little while ago:
http://www.hemenway.com/for_peter/2nd-try-bighorn_blue.jpg

I desaturated the blue by -95 and in color balance I added +25,  Then I
added +10 contrast.  All done in Photoshop but I would guess that you
would have those types of controls in your software

Do you like this any better?  I might have given it too much contrast
with the +10... but, I think that the blue is gone, at least it is on my
monitor.  Try playing with the sliders in your software and the "levels"
if you're feeling adventurous.
