As others have said, Qimage will only output RGB.  I think that most
of us who are using Qimage to prepare input for QTR are turning off
the profile, so that it is an untagged RGB image. It seems that you
have to do this for genuinely grayscale images.  Given the way that
Qimage works, I actually keep my B&W images as monochrome RGB.  I
could attach a profile, but it would be a colour one and I assume that
QTR would ignore it?

Because I've always done it this way, I don't really understand what
QTR does with profiles (since I don't attach one).  If an image has a
profile attached, what does QTR do with the profile?  If Mike got
around to supporting grayscale, and we could tag the output file with
an appropriate profile, what difference would this make?  If I
attached a colour profile to my RGB images, would QTR do anything
with it?

(Sorry if this is a dumb question)
