Digital BW, The Print

My b/w conversions are not gray scale--usually work in channel mixer/mono as a beginning, perhaps hue/saturation layers, dodge/burn layer with overlay/18% grey, adjustment layers, etc. but almost always working in 16 bit RGB (and in my normal ARGB98 working space).  Consequently, I am not in grayscale until I convert to LAB-gray and I use this as my 'proofing' --where I can tweak a bit more for tonality, contrast, etc. if needed (usually not).  I'll try your method--I'm on PC so can't dothe conversions on the fly like Mac though.

  good reason to use
  Lab or Roy's L as a workspace is that because it is Lab's L channel L=50 (ie
  the 50% step) corresponds to Kodak grey.  So if you know that you want a
  certain part of the image to be 18% reflectance then you can work towards it
  easily.  The bottom line is I find Lab (less the a and b) to be more
  intuitive.
