Re: QTR: Great Tool ... no casts, But

Like Fred, I don't fully understand soft-proofing on a PC either.  I
didn't think that the new profiles solved that problem on a PC.  I 
thought that what they did was solve the problem of "linearising", and
thereby solved the problem of compression in the darker tones, and
images looking a little dark & flat.  Even using the profiles, I still
find my images a little dark, and have to use some of the controls in
QTRGui(ink limit adjustment and gamma adjustment) to lighten things up
a bit.  Maybe I need to check the black and white points on my 2100.

If I've misunderstood something, happy to stand corrected.
