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. Lou --- In DigitalBlackandWhiteThePrint@yahoogroups.com, "Nick H.
