A nice feature in this case would be to be able to get the white point 
in an OTHER picture.

With digital photography, I use often raw pictures. At the beginning of 
the shot, I get a picture of a grey/white card which will be the white 
reference for all the following pictures. If the light conditions 
change, I get an other picture of the grey chart and so I never mind of 
the camara white balance, all the wotk is done in post-processing.

So it would be nice to be able to open a white reference picture and 
pick reference from this picture an apply it to the other shots.

Regards

Jean-Luc
