I'm just experimenting with QTR. So far I have found that my image needs to be converted to grayscale with a Gamma of 2.2. I use ProPhoto with a Gamma of 1.8 for my editing so I'm wondering what the correct way to get to grayscale 2.2 is. Do I convert to ARGB, and then mode or do I set my colour settings to Grey Gamma 2.2 and then mode. I would hate to start off doing it the wrong way.
