Hi all.
Question.
Iām trying to study the filmic rgb module more thoroughly and Iām watching Bruce Williamsā lesson - darktable ep 057 - The Filmic RGB module. darktable ep 057 - The Filmic RGB module - YouTube
In it he talks about such a thing as middle-gray luminance in the scene tab.
Maybe you need to switch something in the module to activate this slider? Because I do not see it anywhere.
Looked for a similar topic from Boris, but his titles donāt describe what the lesson will be about. Been reviewing his lessons. There is mention of this video, but a little bit of it everywhere. Of course, I will try to put it all together to clearly understand how the module is set up, but for now I am trying to learn how to work with the tool, based on the lesson, where everything is collected in one video.
This video about Filmic modul from Bruce is very old. Filmic has been improved quite a bit in the meantime.
Middle gray luminance has been discarded because now you control the brightness with exposure module.
You can see some things about Filmic in this video from me:
Itās disabled by reason - you can enable it if you know what youāre doing.
The best practice is to set middle gray via exposure because thatās quite early in the pipe and several module behaves better if middle grey is properly set. There might be usecases to tweak that setting later (e.g. late exposure hangers can affect parametric mask) then it might make sense to do it in filmic.
Thanks for your explanation. It might be more interesting for @anon43125638 since he was wondering where the setting is. I think the two older topics I linked also contain some nice statements about why itās gone. For my part Iāve anyway never used it.
I noticed very often you re order the stack (so the next module is not influenced by the adjustment already done). I am curious - if this re ordering is not done - are you noticing significant change? I am asking because I read somewhere darktable 3.8 user manual - module order that in general DT would handle the order well and rarely reordering of the module is needed.
Also - in some other videos I have seen that photographers adjust a tiny bit the eyes - like size. Is this possible in DT? I tried the liquefy module but it always pushes in one direction. Not sure if I am doing something wrong.
I understand this maybe controversial and even if possible can easily go from barely noticeable to very wrong.
Yeah. Too bad dt canāt process video. I mean log video. So I process video easily by throwing the program tiff files from Davinci. Itās a pity, because I canāt use all power of the program - sharpening, grain manipulation. In filmic rgb I have to turn off iterations of image processing and adding noise to light. The hald file just canāt handle all the retouching.
But this is another topic, not related to this branch, because the work with video is already and support for output boards (deklink the same) and support for control panels (all these balls for adjustments). And in general - this is another topic.
As usual I am a little lost but if you are referring to using DT to edit tiffs spit out from log video and correcting that in DT with a LUT like you would a video editor I think you will likely need to move the LUT module and not use it where it isā¦even then I am not sure exactly where or of the results. You would have to expt. Then maybe depending on what you typically end up with you might find that filmic might not even be what you would want to useā¦its just a global tone mapper
In any case you might find some of the discussion from here touches on this aspect of DTā¦
Nah. You need a separate paint program. From developing the video to interpreting it in rec.709/etc. At the level of coloring, as Darktable, only ābaselightā ( FilmLight | Products | Baselight ) level programs can perform - proprietary of course.
Ok. The following case is a good task to think about:
With Retouch module I would like to improve/change (among other changes) color tone of skin.
But, the retouch module comes hierarchically before the white balance (color calibration module).
