It finally works very well.

I am not at all refusing to acknowledge the accomplishments of so many.
Rather I am praising the very significant progress this represents.  Other
than Imageprint's ICC approach, this is the first "colour-managed" approach
to B&W tonal range management discussed on this forum in the last three
years.  There have been expressed desires, hopes and wishes - but no
implementation.  Yes we have used colour management tools to do proofing but
not for the much more critical management of tonal range.  In the last three
years (other than the discussion building towards QTR Create ICC) there has
been no progress made in the dynamic management of tonal compression other
than to suggest people do an "s-curve".

QTR Create ICC finally takes knowledge that has been available to the colour
world for many years and applies it to B&W.  This is fantastic.

My point was simply to say that even if one didn't have the ability to
deploy a general, colour-managed approach such as QTR Create ICC, one can
achieve the same result with as much rigour for any given workspace by
deploying a "smart(er) linearization".  It's a pity we didn't.  But in the
end we leapfrogged to a workflow (QTR ICC) that works for any workspace -
all's well that ends well.

Congratulations Roy and thanks very much for all the hard work over the last
year.

Steve
