There
are two ways to correct a QTR profile so that the input and output
match in the mid-tones as well as in the shadows and highlights. One of
the methods is with a GRAY_CURVE= command, another is with the
Linearize command. In the Carbon 100 profile, where all curves follow
the K, the Curve K line plays the same role as GRAY_CURVE= so you can linearize the profile with either command.
Also can you explain to me the difference between linearize line and the Curve K ?
