Re: IJC/OPM How do you lighten a profile

2005-02-04 by ldina

Nick,

That is my experience.  If you want to lighten the midtones in your 
profile, just move the slider a few points in the minus direction.  
Your raw data is still plotted on the curve based on the L* or 
density units you originally entered (unless you click the clear 
button, in which case you would need to reenter the data).  So, the 
green curve represents the absolute value and spacing between each of 
the 26 steps after IJC performs auto linearization.  All you need to 
do is save your profile after moving the gamma slider and you will 
have a finished, linearized profile.
