Hi everyone,
There’s so much activity, it’s getting hard to keep track of open questions, to be honest 
One important thing: http://rawpedia.rawtherapee.com/Film_Negative rawpedia entry for filmneg module desperately needs a revision. I’d like to contribute (currently requesting an account on rawpedia). At least, that would help me understand a few more things 
I guess I still need a clear view on the processing pipeline and how it’s integrated into it.
- would you mind telling me more about the filmneg white balance sliders? are they exactly on the same orthogonal axes as the usual sliders? (rawpedia mentions temperature is on the blue/yellow axis… contrary to what @rom9 said about it being blueish (azure?) / amber. It does not change many things, as long as a 30-degree tilt is performed on the tint axis, too)
- is there a way to revert the filmneg WB to the initial median? (sorry for missing that info, if it was shared earlier). It’s not crop-sensitive, right?
- is the filmneg WB sensitive to the order in which the operations are performed? Specifically, say I:
a. do WB with spot tool,
b. adjust “Output level” slider (imagine I’m stupid, I bump it up way too high),
c. maybe try some other WB spot?
==> will it still work properly or will it be biased / sensitive to some channel clipping?
==> same question (but more related to processing pipeline): does it change anything if histogram is stretched with curves and then filmneg spot WB is done again?
Also, the recent discussions about film behaviour with regards to (over)exposure remind me of the lengthy darktable’s Filmic FAQ there are quite a few technical aspects in there, for us, film users, not to forget about how film behaves
