Digital BW, The Print

I added a split toning action to the Hueblending action set that can  
be used as an alternative to blending.  Starting with a grayscale  
image, the SplitToning action will produce an RGB image with warm  
shadows/lower midtones and neutral highlights/upper midtones.  Sample  
image:
