[Digital BW] Re: Culbertson's RGB method A-OK

Scott,

You make a good case and what drew me to the Spectrocam in the first 
place was the scan mode which would speed things up greatly in 
comparision to the Swatchbook at the same price. So I guess I will 
put it back on my list as top a posibility.

Thanks again,

Martin
