[Gimp-user] white balance question

[Boisdesdames <boisdesdames gmail com>]

Hi,

I have a question about the automatic white balance tool applied to a 
portion of a picture (in my case, scans of negative pictures). The tool 
"Colors -> Auto -> White Balance" gives good results most of the time. 
But when the image has strong contrast (for example winter pictures in 
the snow), the result is not that good.
If I select a portion of the picture (rectangular selection tool for 
example) and apply the automatic white balance, the result is better but 
is only applied to the selected region of the picture. Is there a way to 
apply these settings to the whole picture ?
