Sure, it’s this one: Filmic, when to use?
Yes, this is the dance I was speaking of, and to be honest, I’m not a fan. Maybe I need to get used to it more, but generally I want to set a slider and not have to return to it after adjusting another one. I can already hear legions of new users complaining about a module like this if they are used to simple exposure and contrast sliders.
I’m liking the results of AgX but I’m still not yet convinced about the slider functionality for my workflow. As @Popanz noted, all the tone mappers have their pros and cons, and I think my ideal would somehow be a merger of them. These are just my preferences though, and I’ll keep playing to improve my understanding of it!
