Hello,
I understand that Darktable shows all the steps necessary before we can start editing. There are11 steps (when you open a RAW in darkroom).
However, the 5 first are always on (then mandatory), but the 6 to 11 can be switched off… means they are not mandatory.
Is it possible to not have these steps (6 - White balance to 11 orientation) added by default ? Or they MUST be added no matter what ?
Thanks
Change processing in preferences to none…this will give you the min number of modules. Selecting legacy will get rid of one more and use traditional WB…if that is your intent??
So you will normally see 11 and using none will drop exposure and filmic… legacy will drop color calibration…
Is it the entry in Treatment / default workflow : scene related / display related / none ?
Otherwise can you point out in which section in the settings ?
Processing - auto apply pixel defaults… display, scene, none…
But do keep in mind that those modules are activated for a reason:
white balance, (most) images will look very greenorientation images in protrait format will not be in the right orientationhighlight recovery overexposed regions can/will turn into a magenta colour (related to the whitebalance setting: red and blue have multipliers >1, and red+blue= magenta)The last one (highlight recovery) is arguably not strictly necessary in all cases if you know how to handle slight clipping in small zones.
exposure and filmic (or basecurve, if you pick ‘display related workflow’) help you to get a better looking image; depending on your images and workflow, they might not be necessary.color calibration is a theoretically better place to set the final white balance.Those six modules are not necessary to obtain a displayable image, but without them the result is not something you’d want to look at. But they can be switched off either because there are alternatives for them, or you may want to inspect the image without one or all of them, or there are some situations where they are not needed/useful.
My suggestion would be to leave those modules activated (or use an alternative, if available), unless and until you have a reason to switch them off.
Thank for the reminder 
In fact you read my mind. My next step was possibliy to replace these module or customize them. This means how you I set my own default set of modules (either autmaically, or through some “macro”.
You can set an auto preset for each module and decide say for which camera or lens or file type etc that you will apply this… so say some custom settings for filmic…
You can also use styles but they cannot be auto applied perhaps with scripting they could…
If you bear in mind you can save deactivated modules in a style, then some people will add all the modules that they normally use for an edit with the settings that are to their liking (so a custom style) and then disable the ones that might be optional on some edits (eg local contrast) before saving the style. Then you apply the style with all the tweaked active modules to your images and then activate the additional modules as needed for individual edits…Styles cannot be auto applied but it is fairly easy to select a group of images and apply a given style…on the other hand any auto presets that you save can be auto applied so if you work through and configure them you can set a bunch of them to be auto applied with your desired settings…
Thank you for the explanation
I edited it and tried to be more clear…
