I’m quite sure that in a previous version of ART I was able to apply the ‘Color/Tone Correction’ module after applying the ‘Black-and-White’ module (or any de-saturation step).
Background: I do (more often lately) editing of scanned film negatives and I’d like to “give a shade to the ink”. In order to do this, a method that is very interesting (because it creates a very good starting point with a “flat” white) is to de-saturate the picture (aka convert to grayscale), and then colorize through parametric masks. This way you can give a color to the ink and/or to the paper (I’m sort of reproducing in a digital way the darkroom printing of film negatives). A part from having a lot of fun, I get very good results with this approach.
So, back to ART… it seems now that after I de-saturate (either with the ‘Black-and-White’ module or with the ‘Saturation/Vibrance’ module) the ‘Color/Tone Correction’ module doesn’t have any effect on color anymore (the output stays grayscale).
I guess this is because in the newer version the modules have been reshuffled such that conversion to grayscale is done as last step?
Or is there a way to get back to this method?
I’m rather sure it worked in the described way before, I have some presets and so (not saying this was the intended way of working though 
). I don’t remember which exact version was that worked like that (and I won’t be able to figure out for another 10 days, before I get back home…)
It’s not a show stopper, I can develop to grayscale in ART and then “colorize” for instance in GIMP, but I preferred when I could do everything in ART (also because I love the masking much more than in GIMP)…
Is there a way to get back to that effect?
Or maybe there is something else I’m missing now… (another difference is that now I’m on Windows, since I’m on a borrowed PC, while before I always used ART in Linux, but I’m quite sure this is not the cause)
well, not a problem any more (…maybe never was…)
