Use the black patches in the software to adjust the black level  
control visually, if you prefer, before using the B&C controls in the  
standard manner. Just keep in mind that more open shadows are only  
more open, not necessarily more correct or more representative. Those  
insisting they should be able to diatinguish 0,0,0 from 2,2,2 on  
screen are not creating a better match, only a more open bottom end.
