I apologise in advance if this is a dumb question...
If Pro Photo uses a gamma of 1.8, and if most of the work you do is in Lightroom and Photoshop; shouldn't one calibrate the display to Gamma 1.8 instead of 2.2?
I have, as per Jeff Schewe and Andrew Rodney, set Photoshop to 1.8. - but what happens in Lightroom?
Thanks!
William.
