Roy, I was printing with an earlier version of
QTR last Spring when I bought it and then did not do much b/w printing for
awhile. I also unsubbed to this mail list so think I missed some things.
As I recalled, the workflow for best prints
was to process 'however' (I use a variety of ways), but to convert to a
grayscale profile before printing. Has that all gone by the boards with
the new version? Or--do I not remember the workflow correctly? (always
possible LOL). I have 3 QTR profiles--lab, matte and photo paper.
Are these obsolete--or do I need to review the conversion/printing
process?
Thanks,

If you shoot the picture in color there's certainly some benefit in retaining that
color info in Photoshop. But the actual input to QTR is always grayscale. If you send
a color image a conversion to grayscale is done automatically using a simple default
conversion. I think in general you'd benefit by controlling that color-to-gray
conversion using Channel Mixer or other techniques. If you do that, you get an RGB
file that is gray i.e. R=G=B. This contains no more information than a grayscale image.
It will be identical data but three times the size. The print result will be identical.
Whether or not you explicitly convert or not is just a matter of convenience.
