Digital BW, The Print

Thomas-

Congratulations... You just joined the "Internet Spirits" (a team of 
honor).

I can't wait to try these (though I'm just getting used to using 
Paul's curves and probably won't be creating anything too unique for 
some time... This is the kind of development that Piezography would 
benefit from if it welcomed it...
