Hi Lou,

Yes. The entered linearization data is fixed. It's the aim slider 
value that is stored in the profile that tells OPM how to adjust the 
output gamma.

Peter has a question about the exposure slider which I haven't played 
with much at all. Does the OPM brightness slider work like the aim 
slider?

I asked Joe Berndt about the possibility of adding a way to tweak the 
aim curve like a Photoshop curve. The OPM constrast slider gives me 
additional constrast but I like the characteristic of Paul Roark's 
curve for the 1160/FS/Mild-EEM combination. I will boost the OPM 
constrast curve and compare it with Paul's curve to see how close 
they are. But being able to tweak the aim curve will make it much 
easier to fine tune a profile for a particular type of image.
