The tool tip upon mouse hover over DCP Tone Curve & Look Table I’m seeing for rawtherapee-5.2 states, “Employ the embedded DCP tone curve. The setting is only enabled if the selected DCP has a tone curve.” The same for Look Table.
I think I now see what the mouse hover-over tooltip statement is likely trying to state, the option will be enabled (but not activated), allowing the user to activate the option per their choice.
“Employ the embedded DCP tone curve. The setting (is disabled by default and) can be activated only if the selected DCP has a tone curve.”
I tend to agree concerning “better looking”. Beauty is in the eye of the beholder.
Regardless… think Morgan already instituted a change on this. Yup, checking GIT, I can see he implemented the term, “available”. Sounds good to me!
