Well you could edit the suitable separation image file (7 
channels) that it resembles a low key image. Say take the 
tone range to 1/3 of the original with PS curves and save 
that with the same name. Of course you kept the original 
file in another map to reinstall it when the experiment is 
done. The files are in the bin map of QTR's program files.
