I do like reading too, but I have to say that Robert's tutorials are really what gave me the taste of darktable. Obviously, the user-manual is a must-read, but it usually tells you *what* things are doing more than *how* and *when* to use them. To anwser one of your initial questions: > * There are different ways to change how bright an image is, at > least two are obvious: > > - `Contrast Brightness Saturation/brightness` and those listed > in the manual there [1]. > > - `Exposure/exposure` > > Which one should I use for which task, i.e., what is the concept > behind “changing brightness” as opposed to “changing exposure”? exposure comes early in the pipeline. It's good because at that stage, you're still really close to the real RAW information, over/under exposed parts of the image have not been cliped other than by the limits of your camera. That's usually where you should start. Contrast Brightness Saturation/brightness comes almost at the end, IIRC in the target colorspace. It may help fine-tuning your settings, but can't recover things that got lost elsewhere in the pipeline. Actually, it is a relatively recent feature of darktable, people lived without it for a while. I almost never use it. -- Matthieu Moy http://www-verimag.imag.fr/~moy/ ------------------------------------------------------------------------------ _______________________________________________ Darktable-users mailing list Darktable-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/darktable-users
