If there's one mailing list and group of people that could
promote a perceptual greyscale curve for use in B&W
photography it should be this list. Roy gave us that space and
it is closer to human visual response than any of the gamma
(old photography attempt to perceptual) and dotgain
(completely different concept) choices.

I know that Gamma 2.2 works and isn't in contradiction with
the rest of the workflow but why not promote a conversion to
the QTR space as it is available ?
