Re: filmscanners: Blue noise - suggestions for removal?

I could deal with the blue of the fringe but not the darkness of the fringe:

 

(Using Corel PhotoPaint) I changed to LAB mode, then adjusted the tone curve of channel B (the blue-yellow continuum channel):  I raised the middle of the curve from 0-0 coordinates to about 0-+2 or 3 on a scale of 0 to 60 each direction so that's about 2-3%.

 

To eliminate extra yellow in the cheeks I then decreased the upper (right) hald of the new curve by about the same amount, bringing the curve there back to about +30-+30.

 

The result is attached.

| My apologies in advance to digest readers for the attached image.  
I've cut
| it down to 6K to minimise the uuencoded text.
| The attached 
photo is the result of a really icky combination of film and
| light.  
The film is Kodak 320T tungsten balanced slide film, and I've taken
| the 
photo by flash - which is of course daylight balanced...  The result 
is
| the ugly blue shadows.  I've managed to remove most of the colour 
imbalance
| from the original slide, but does anyone have any suggestions for 
removing
| the blue fringing?

| Yes I know it's grainy but on 
this occasion I'm not worried about the grain.
| :)  It's 320 speed 
slide film after all.
