Digital BW, The Print

Steve, try Convert to B&W Pro at www.theimagingfactory.com.  It's pretty
cool, and effortless.  You can pick the "film" you want (TriX, FP4 etc.),
the filter, and the paper grade. Often after converting the b&w image I will
tone it with a hue-saturation layer and the TZ-BWTone filters (platinum,
kallitype, lots).

Regards,
