Digital BW, The Print

Russ, if the saturation function yields the results you desire,
do it, then go to the history tab, create a history layer with it, 
trash the saturation history step. Click the box on the new history 
layer to make it active, and use the history brush to paint in the 
color adjustment just where you want it.
I have been using this for a lot of 16 bit contrast adjustments in
PhotoShop 5.

Best,
Alex
