Hello Graeme und Florian, (Klaus, Gerard, Edmund, the rest too ...) In preparing for my class tomorrow, I experimenting with dispcal and Florian's excellent dispcalGUI. At the end of calibrating, choice message comes up with "Install" and "Don't install" profile. In the same window is an option called "Show LUT curves" that, when checked, displays the RGB calibration curves in a separate window -- I love this. But could there be an option for saving the LUT curves for later studying? Best / Roger
